Description

Technical Field

[0001] This utility model relates to the field of sanitation vehicle technology, and in particular to a sanitation vehicle sweeping brush. Background Technology

[0002] Sanitation vehicles are specialized vehicles used for urban sanitation and cleaning. They are a new type of efficient cleaning equipment that integrates road sweeping, garbage collection and transportation. Equipped with sweeping brushes and other cleaning systems, these specialized sanitation vehicles are mainly used by sanitation departments in large and medium-sized cities for cleaning operations. Sanitation vehicles greatly reduce the workload of sanitation workers, improve work efficiency, and reduce secondary pollution such as dust. Sanitation vehicles are mainly divided into water sprinkler trucks and garbage trucks. Water sprinkler trucks are generally equipped with sweeping disc structures.

[0003] Currently, the sweeping discs on sanitation vehicles operate by first driving a gear pump with a motor, which then activates the motor via a hydraulic drive mechanism. The motor then rotates the sweeping discs. While the combination of the motor, gear pump, and sweeping discs enables rotation during operation, the existing cover plates are bolted in place. This causes the brushes to rotate and vibrate during use, leading to deformation and loosening of the mounting joints over time, thus affecting cleaning performance. Current equipment primarily replaces loose brushes, lacking the long-term reinforcement and tightening effect. Utility Model Content

[0004] This utility model provides a sanitation vehicle sweeping brush that solves the technical problem that ceiling fans generate periodic vibrations during continuous operation. These forces act continuously on the movable frame, and over time, they accumulate enough to gradually loosen the fastening points of the movable frame. When the ceiling fan is restarted and runs at high speed, the ceiling fan body will shake.

[0005] The purpose and effect of this utility model for a sanitation vehicle sweeper are achieved by the following specific technical means: A sanitation vehicle sweeper includes a sweeper plate, sweeper blades disposed at the bottom end of the sweeper plate, and mounting posts disposed at the top end of the sweeper plate.

[0006] The protective shell is mounted on the mounting post and located at the top of the brush plate;

[0007] The protective circuit is installed on the outer wall of the protective casing.

[0008] Preferably, the protective shell is a hollow cylinder, and the internal dimensions of the protective shell are adapted to the external dimensions of the brush plate.

[0009] Preferably, the protective shell has a through mounting hole inside, and the internal size of the mounting hole is adapted to the external size of the mounting post.

[0010] Preferably, a lower spring plate is provided on the mounting post and at the top of the protective shell, and an upper spring plate is provided at the top of the lower spring plate and on the mounting post. Both the lower spring plate and the upper spring plate are in the shape of a round cap.

[0011] Preferably, the protective line is in the shape of a multi-U shape, and protective components are provided on the protective line.

[0012] Preferably, the protective component includes an alarm box, an alarm, an alarm power supply, a resistor, and a branch line. The alarm box is disposed on the protective line, and an alarm power supply is disposed inside the alarm box. A resistor is disposed on one side of the alarm power supply and inside the alarm box, and the other side of the alarm power supply and the side of the resistor away from the alarm power supply are both connected to the protective line.

[0013] Preferably, a branch line is provided on the protective line and inside the alarm box. Both the branch line and the protective line are provided with electrical wires. An alarm is provided on the branch line and the alarm is fixedly installed on the top of the alarm box.

[0014] Preferably, the brush blades are arranged in a circular array, and the brush plate is fixedly connected to the sanitation vehicle mounting location via mounting columns.

[0015] Beneficial effects:

[0016] 1. With the protective shell in place, the mounting post first passes through the mounting hole, and then through the lower spring plate and the upper spring plate in sequence to be installed and fixed at the working position of the sanitation vehicle. The lower spring plate and the upper spring plate will be squeezed and exert a squeezing and expanding force on the installation point of the sanitation vehicle and the sweeping brush plate below, so that the bolts used for installation and fixing are not easy to loosen.

[0017] 2. The protective circuit is set up around the brush plate to protect it. When the brush plate is damaged by collision, the protective circuit will be damaged first. The internal circuit of the protective circuit is damaged and cannot carry current. The current flows through the branch line, through the alarm, and back to the negative terminal of the alarm power supply. The alarm will start to play and issue a warning, automatically reminding people that the broom has been damaged by collision and needs to be replaced. Attached Figure Description

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] First Embodiment

[0027] As attached Figure 1 Appendix Figure 2 and attached Figure 3 As shown: A sanitation vehicle sweeper includes a sweeper plate 1, sweeper blades 9 disposed at the bottom end of the sweeper plate 1, and mounting posts 5 disposed at the top end of the sweeper plate 1.

[0028] The protective shell 2 is mounted on the mounting post 5 and located at the top of the brush plate 1. The protective shell 2 is a hollow cylinder. The internal size of the protective shell 2 is adapted to the external size of the brush plate 1. The protective shell 2 is installed between the lower spring plate 4 and the brush plate 1 to provide protection.

[0029] The protective shell 2 has a through mounting hole 7 inside. The internal size of the mounting hole 7 is adapted to the external size of the mounting post 5. When replacing the sweeping brush, the mounting post 5 first passes through the mounting hole 7, and then passes through the lower spring plate 4 and the upper spring plate 3 in sequence. As the sweeping brush 1 is installed and fixed in the working position of the sanitation vehicle, the lower spring plate 4 and the upper spring plate 3 will be squeezed and deformed. At the same time, the force of squeezing and expanding is applied to the installation position of the sanitation vehicle and the lower sweeping brush 1, so that the bolts used for installation and fixing are not easy to loosen.

[0030] A lower spring plate 4 is provided on the mounting post 5 and at the top of the protective shell 2. An upper spring plate 3 is provided at the top of the lower spring plate 4 and on the mounting post 5. Both the lower spring plate 4 and the upper spring plate 3 are round cap-shaped.

[0031] Second Embodiment

[0032] As attached Figure 1 , Figure 4 and attached Figure 5 As shown: the protective line 6 is set on the outer wall of the protective shell 2; the protective line 6 is in the shape of multiple U-shapes, and the protective component 8 is set on the protective line 6. When the brush is working normally, the protective line 6 plays a protective role around the brush plate 1.

[0033] The protective component 8 includes an alarm box 801, an alarm 802, an alarm power supply 803, a resistor 804, and a branch line 805. The alarm box 801 is located on the protective line 6. The alarm power supply 803 is installed inside the alarm box 801. The resistor 804 is installed on one side of the alarm power supply 803 and inside the alarm box 801. The other side of the alarm power supply 803 and the side of the resistor 804 away from the alarm power supply 803 are both connected to the protective line 6. When the brush is working normally, the current of the alarm power supply 803 in the alarm box 801 starts from the positive terminal, passes through the resistor 804, and returns directly to the negative terminal from the protective line 6. The alarm 802 is in an inactive state.

[0034] A branch line 805 is installed on the protective line 6 and inside the alarm box 801. Both the branch line 805 and the protective line 6 have electrical circuits inside. An alarm 802 is installed on the branch line 805 and is fixedly installed on the top of the alarm box 801. When the brush is damaged by a collision, the protective line frame 6 will be damaged first. The electrical circuit inside the protective line 6 is damaged and cannot carry current. The current flows from the branch line 805 through the alarm 802 and back to the negative terminal of the alarm power supply 803. The alarm 802 starts to work and issues a warning, automatically reminding personnel that the brush has been damaged by a collision.

[0035] The sweeping brush blades 9 are arranged in a circular array. The sweeping brush plate 1 is fixedly connected to the sanitation vehicle installation location through the mounting column 5. When changing the installation structure of the sweeping brush, the sweeping brush plate 1 and the sweeping brush blades 9 need to be replaced frequently. The protective shell 2, the lower spring plate 4 and the upper spring plate 3 can be reused.

[0036] Working principle: When replacing or installing the sweeping brush, the mounting post 5 first passes through the mounting hole 7, and then through the lower spring plate 4 and the upper spring plate 3 in sequence. As the sweeping brush plate 1 is installed and fixed in the working position of the sanitation vehicle, the lower spring plate 4 and the upper spring plate 3 will be squeezed and deformed. At the same time, the force of squeezing and spreading is applied to the installation position of the sanitation vehicle and the lower sweeping brush plate 1, making it difficult for the bolts used for installation and fixing to loosen. The protective shell 2 is installed between the lower spring plate 4 and the sweeping brush plate 1 to play a protective role. When the sweeping brush is working normally, the protective circuit 6 plays a protective role around the sweeping brush plate 1. The current of the alarm power supply 803 in the alarm box 801 starts from the positive terminal, passes through the resistor 804, and returns directly to the negative terminal from the protective circuit 6. The alarm 802 is in an inactive state. When the sweeping brush is damaged by collision, the protective circuit frame 6 will be damaged first. The electrical circuit inside the protective circuit 6 is damaged and cannot carry current. The current passes through the branch line 805, through the alarm 802, and then returns to the negative terminal of the alarm power supply 803. The alarm 802 starts to work and issues a warning, automatically reminding personnel that the sweeping brush has been damaged by collision.
