Abstract
Description
Technical Field
[0001] This solution belongs to the field of dust control devices, specifically involving an adjustable-angle dust control device for municipal construction. Background Technology
[0002] A large amount of dust is easily generated during municipal construction, so dust control devices are needed to remove it.
[0003] A search revealed a utility model patent with authorization announcement number CN221867851U, which discloses a dust suppression device for municipal public works construction. The device includes a water tank with handrails fixedly installed on its side walls and supports fixedly installed on both sides of the top of the tank. Each support has a lead screw rotatably connected inside, and a motor is fixedly installed on the top of one of the supports. The output end of the motor is fixedly connected to one of the lead screws. However, in existing technologies, the orientation is relatively fixed, resulting in a relatively limited dust suppression range. This not only increases the dust suppression cycle but also wastes water resources. Utility Model Content
[0004] The purpose of this solution is to provide an adjustable-angle dust suppression device for municipal construction, in order to solve the problem that the existing technology has a relatively fixed orientation, which leads to a relatively limited dust suppression range.
[0005] To achieve the above objectives, this solution provides an adjustable-angle municipal construction dust control device, including a water tank. A fixed base is fixedly connected to the top of the water tank. An adjusting shaft is installed inside the fixed base via a bearing. A connecting seat is movably connected to the outer side of the adjusting shaft. A spray gun is fixedly connected to the top of the connecting seat. A water pump is installed at the bottom inner side of the water tank. The output end of the water pump passes through the water tank and extends to the outside of the water tank. A connecting pipe is fixedly connected to the end of the output end. The end of the connecting pipe is connected to the spray gun. A locking disc is fixedly connected to the adjusting shaft. A locking mechanism is provided inside the fixed base. A limiting plate is fixedly connected to the connecting seat. A support frame is fixedly connected to the locking disc. An electric push rod is fixedly installed on the support frame. The telescopic shaft of the electric push rod passes through the limiting plate and is slidably connected to the limiting plate.
[0006] The principle of this solution is as follows: When in use, first fill the water tank with water, then push the entire unit to move it to the predetermined position. After moving to the predetermined position, the water pump delivers clean water from the water tank to the spray gun through the connecting pipe, and finally sprays it out to reduce dust at the construction site. At the same time, the telescopic shaft of the electric push rod repeatedly extends and retracts. The limit ball on the telescopic shaft applies a pushing and pulling force to the limit plate, which allows the spray gun to repeatedly deflect at a certain angle through the connecting seat and the adjusting shaft, thereby expanding the dust reduction range of the spray gun. In addition, by pulling the locking pin with the lever, the locking pin is separated from the locking disc. In this way, the adjusting shaft can be rotated to adjust the direction of the spray gun. Finally, the locking pin is reinserted into the locking disc.
[0007] The technical advantage of this solution is as follows: A fixed base is installed on the top of the water tank, and an adjusting shaft is mounted on the fixed base using a bearing. A matching connecting seat is installed on the top of the adjusting shaft, and the spray gun is fixed to the fixed base. Then, a locking disc and a locking mechanism are respectively installed on the adjusting shaft and the fixed base. The locking pin in the locking mechanism is inserted into the locking disc under the action of a spring. At the same time, a ring of grooves is opened on the locking disc. In this way, by engaging the locking pin with the grooves at different positions, the orientation of components such as the adjusting shaft, the connecting seat, and the spray gun can be adjusted, thereby adjusting the direction of dust prevention.
[0008] By setting a Z-shaped support frame on the lock plate, installing an electric push rod on the support frame, and then setting a limiting plate on the connecting seat, the telescopic shaft of the electric push rod passes through the limiting plate, and two limiting balls are set on the telescopic shaft. In this way, by repeatedly extending and retracting the telescopic shaft of the electric push rod, and then applying a pushing and pulling force to the limiting plate through the limiting balls, the spray gun can be repeatedly deflected at a certain angle through the connecting seat and the adjusting shaft, thereby expanding the dust suppression range of the spray gun.
[0009] Furthermore, the connecting seat is equipped with a second type of ball bearing, which contacts the adjusting shaft. The inclusion of the second ball bearing reduces the relative friction between the connecting seat and the adjusting shaft.
[0010] Furthermore, two limiting balls are fixedly connected to the shaft of the telescopic shaft, and the two limiting balls are located above and below the limiting plate, respectively. The limiting balls apply a pushing or pulling force to the limiting plate.
[0011] Furthermore, a ball bearing is provided at the bottom of the support frame, and the ball bearing contacts the water tank. The ball bearing assists in the rotation of the support frame.
[0012] Furthermore, a rubber stopper is slidably connected to the top of the water tank, and the stopper extends through the tank. This rubber stopper facilitates the replenishment of water to the tank later.
[0013] Furthermore, a push handle made of stainless steel is welded to the right side of the water tank. The push handle facilitates the application of pushing force to the entire tank, which, in conjunction with the wheels at the bottom of the tank, allows for positional movement.
[0014] Furthermore, the locking mechanism includes a locking pin slidably connected inside the fixed base. The locking pin is inserted into the locking disc. A spring is installed inside the fixed base, with one end of the spring fixedly connected to the locking pin and the other end fixedly connected to the inner surface of the fixed base. A lever is fixedly connected to the pin body of the locking pin, and the lever is slidably connected to the fixed base. A locking arm is hinged inside the fixed base, and the end of the locking arm engages with the lever. A pull ring is fixedly connected to the locking arm. Through the design of the locking mechanism, in conjunction with the locking disc, it provides an orientation adjustment function for components such as the adjusting shaft, connecting seat, and spray gun.

Detailed Implementation
[0021] The basic implementation examples are as follows: Figures 1-4The image shows an adjustable-angle dust suppression device for municipal construction, comprising a water tank 1. A fixed base 2 is fixedly connected to the top of the water tank 1. An adjusting shaft 3 is mounted inside the fixed base 2 via bearings. A connecting seat 4 is movably connected to the outer side of the adjusting shaft 3. A ball bearing 12 is installed inside the connecting seat 4, and the ball bearing 12 contacts the adjusting shaft 3. The ball bearing 12 reduces the relative friction between the connecting seat 4 and the adjusting shaft 3. A spray gun 5 is fixedly connected to the top of the connecting seat 4. A water pump 13 is installed at the bottom inner side of the water tank 1. The output end of the water pump 13 passes through the water tank 1 and extends to the outside of the water tank 1. A connecting pipe 14 is fixedly connected to the end of the output end, and the end of the connecting pipe 14 is connected to the spray gun 5. A locking disc 6 is fixedly connected to the adjusting shaft 3. A rubber stopper 16 is slidably connected to the top of the water tank 1, and the rubber stopper 16 penetrates the water tank 1. The rubber stopper 16 facilitates the replenishment of water to the water tank 1 at this location. A push handle 15, made of stainless steel, is welded to the right side of water tank 1. The push handle 15 facilitates the application of pushing force to the entire tank, which then moves the tank in position in conjunction with the wheels at the bottom of the tank.
[0022] like Figure 2 , Figure 3 As shown, a limiting plate 11 is fixedly connected to the connecting seat 4, and a support frame 8 is fixedly connected to the locking disc 6. A ball bearing 81 is located at the bottom of the support frame 8, and the ball bearing 81 contacts the water tank 1. The ball bearing 81 assists in the rotation of the support frame 8. An electric push rod 9 is fixedly installed on the support frame 8. The telescopic shaft of the electric push rod 9 passes through the limiting plate 11 and is slidably connected to it. Two limiting balls 10 are fixedly connected to the shaft, and the two limiting balls 10 are located above and below the limiting plate 11, respectively. The limiting balls 10 apply a pushing or pulling force to the limiting plate 11.
[0023] like Figure 3 , Figure 4 As shown, the fixed base 2 is equipped with a locking mechanism 7. Through the setting of the locking mechanism 7, it cooperates with the locking disc 6 to adjust the orientation of components such as the adjusting shaft 3, the connecting seat 4, and the spray gun 5. The locking mechanism 7 includes a locking pin 71 that is slidably connected inside the fixed base 2. The locking pin 71 is inserted into the locking disc 6. The fixed base 2 is equipped with a spring 72. One end of the spring 72 is fixedly connected to the locking pin 71, and the other end of the spring 72 is fixedly connected to the inner surface of the fixed base 2. A lever 73 is fixedly connected to the pin body of the locking pin 71. The lever 73 is slidably connected to the fixed base 2. A locking arm 74 is hinged inside the fixed base 2, and the end of the locking arm 74 is engaged with the lever 73. A pull ring 75 is fixedly connected to the locking arm 74.
[0024] The specific implementation process of this utility model is as follows: When in use, first fill the water tank 1 with water, and then push the whole unit to move by pushing the handle 15. After moving to the predetermined position, the water pump 13 transports the clean water in the water tank 1 to the spray gun 5 through the connecting pipe 14, and finally sprays it out to reduce dust at the construction site. At the same time, the telescopic shaft of the electric push rod 9 repeatedly extends and retracts. The limiting ball 10 on the telescopic shaft applies a pushing and pulling force to the limiting plate 11, which allows the spray gun 5 to repeatedly deflect at a certain angle through the connecting seat 4 and the adjusting shaft 3, thereby expanding the dust reduction range of the spray gun 5. In addition, by pulling the locking pin 71 by the lever 73, the locking pin 71 is separated from the locking disc 6. In this way, the adjusting shaft 3 can be rotated to adjust the orientation of the spray gun 5. Finally, the locking pin 71 is reinserted into the locking disc 6.
[0025] This solution involves setting a fixed base 2 on the top of the water tank 1, mounting an adjusting shaft 3 on the fixed base 2 using bearings, and setting a matching connecting base 4 on the top of the adjusting shaft 3. The spray gun 5 is then fixed on the connecting base 4. A locking disc 6 and a locking mechanism 7 are respectively set on the adjusting shaft 3 and the connecting base 4. The locking pin 71 in the locking mechanism 7 is inserted into the locking disc 6 under the action of the spring 72. At the same time, a ring of grooves is opened on the locking disc 6. In this way, by engaging the locking pin 71 with the grooves at different positions, the orientation of components such as the adjusting shaft 3, the connecting base 4, and the spray gun 5 can be adjusted, thereby adjusting the direction of dust prevention.
[0026] By setting a Z-shaped support frame 8 on the lock plate 6, installing an electric push rod 9 on the support frame 8, and then setting a limiting plate 11 on the connecting seat 4, the telescopic shaft of the electric push rod 9 passes through the limiting plate 11, and two limiting balls 10 are set on the telescopic shaft. In this way, by repeatedly extending and retracting the telescopic shaft of the electric push rod 9, and then applying a pushing and pulling force to the limiting plate 11 through the limiting balls 10, the spray gun 5 can be repeatedly deflected at a certain angle through the connecting seat 4 and the adjusting shaft 3, thereby expanding the dust suppression range of the spray gun 5.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model.
