Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

For example, they can refer to fixed, removable, or integral connections; mechanical or electrical connections; direct connections or indirect connections through an intermediary; or internal connections between two components. Those skilled in the art will understand the specific meanings of these terms in this application in specific contexts.

[0037] Example

[0038] Please refer to Figures 1-8The utility model provides an automatic spraying device, including a fixed shell 1, a sealing gasket 2, a detector 3, a chamber pump pressure structure 4, an adsorption structure 5, and a spray agent pipeline structure 6.

[0039] Furthermore, a fixed outer shell 1 is connected to the outer surface of the pipeline to protect the parts of the pipeline that are prone to leakage and damage, thereby reducing the impact of the external environment.

[0040] Sealing pads 2 are provided at the joints between the fixed shell 1 and the two ends of the pipe, so that a closed space is formed between the fixed shell 1 and the pipe to prevent the sprayed mist from escaping to the outside of the pipe when the device sprays the pipe there.

[0041] Furthermore, at least one detector 3 is provided on the end face of the fixed shell 1. The detection head of the detector 3 is inserted into the confined space. The detection direction of the detection head is along the length direction of the pipeline to detect the outside of the pipeline, so as to detect whether there is a spray agent (mist) in the confined space outside the pipeline and whether the spraying function is normal.

[0042] It is worth noting that the aforementioned detector 3 is comprised of a laser sensor. The laser sensor emits a laser beam, which is then reflected to achieve detection. When spraying agent within a confined space, the concentration of the mist gradually increases until it blocks the laser beam, at which point the laser sensor detects the spray. The principles and structure of the aforementioned detector are basic common sense within the skill of those skilled in the art and are therefore not described in detail in this specification.

[0043] Furthermore, a chamber pumping structure 4 is provided in the enclosed space, which is responsible for pumping the spraying agent into the pipeline in the enclosed space.

[0044] The chamber pump pressure structure 4 includes a storage chamber 401, a chamber outlet 405 and a pump pressure device. Spraying agent is stored in the storage chamber 401. The storage chamber 401 pumps the spraying agent to the chamber outlet 405 through the pump pressure device. The chamber outlet 405 is connected to an atomizing head. The atomizing head is then directed to the enclosed space outside the pipeline. A plurality of atomizing heads are evenly arranged along the axial direction of the pipeline. When the pipeline is sprayed, the pump pressure device is started, and the spraying agent in the storage chamber 401 is sprayed into the enclosed space outside the pipeline through the atomizing head to achieve atomization, and the mist-like spraying agent will slowly adhere to the outer wall of the pipeline for uniform coverage. Compared with smearing, the uniformity of the mist-like spraying agent coverage is better. When not spraying, the pump pressure device does not work, and the pressure valve carried in the atomizing head is not subjected to pressure. The pressure valve closes the atomizing channel of the atomizing head to prevent the spraying agent from overflowing.

[0045] Furthermore, an adsorption structure 5 is provided in the confined space, which is located between the chamber pump pressure structure 4 and the pipeline. When the spray agent in the confined space outside the pipeline is covered, there will still be residual mist spray agent. At this time, it will be quickly adsorbed and gathered by the adsorption structure, so that the coating agent covering the outside of the pipeline can accelerate drying.

[0046] A spray agent pipeline structure 6 is further provided outside the fixed housing 1 . The spray agent pipeline structure 6 is connected to the storage chamber 401 through a pipeline, and the other end of the pipeline is connected to the spray agent storage tank.

[0047] When spraying the spray agent, the chamber pump pressure structure 4 will spray the spray agent in the storage chamber 401 to the enclosed space outside the pipeline, covering the pipeline with spray. At this time, due to the decrease in the air pressure in the storage chamber 401, the spray agent in the spray agent tank will enter the storage chamber 401 through the pipeline, making it easier for the subsequent pump pressure device to continue spraying the spray agent into the pipeline.

[0048] In this embodiment, the fixed housing 1 includes a supporting housing 101 and a mounting plate 102 .

[0049] Specifically, the support shell 101 is cylindrical and is composed of two semi-cylinders, which is convenient for installation on the outside of the pipe. Each semi-cylinder is respectively matched with a mounting plate 102. The mounting plate 102 is provided with multiple threaded holes. The support shell 101 can be sleeved on the pipe by tightening the screws.

[0050] By loosening the screws, the device can be separated from the pipe, making it easier to move the device from the pipe that has been sprayed to the pipe that has not been sprayed.

[0051] In this embodiment, the chamber pumping structure 4 further includes a cylinder 402 , a connecting plate 403 , a piston plate 404 , and a sliding rod 406 .

[0052] Specifically, the storage chamber 401 is fixed on the inner wall of the cylindrical supporting shell 101 and is an annular chamber. A plurality of baffles are provided in the annular chamber, which divide the annular chamber into four separate identical arc-shaped chambers.

[0053] By dividing the material storage chamber 401 into a plurality of smaller arc-shaped chambers, the pumping pressure of the pumping device is reduced, and the smoothness of the pumping is improved, so that the spraying agent can be pumped out quickly.

[0054] A cylinder 402 is arranged between the baffles between two adjacent arc-shaped chambers. The push rod of the cylinder 402 is fixed to the connecting plate 403. The two ends of the connecting plate 403 are respectively connected to a piston plate 404. Each piston plate 404 is slidably set in a different arc-shaped chamber. The piston plate 404 matches the chamber shape of the arc-shaped chamber, and the sliding direction of the piston plate 404 is consistent with the length direction of the pipeline.

[0055] The cylinder 402, the connecting plate 403 and the piston plate 404 constitute a pumping device.

[0056] When the push rod of the cylinder 402 moves, the piston plate 404 slides in the arc-shaped chamber, pushing the spraying agent stored in the chamber to spray from the chamber outlet 405 into the closed space outside the pipeline.

[0057] In addition, piston plates 404 are provided at both ends of the arc-shaped chamber. The piston plates 404 at each end are connected to the push rods of the cylinder 402 provided at that end. The push directions of the push rods of the cylinder 402 connected to the piston plates 404 at both ends are opposite.

[0058] Two adjacent cylinders 402 are positioned in opposite directions, with piston plates 404 at either end of the arc-shaped chamber between them connected to the two cylinders 402. During spraying, each cylinder 402 drives the piston plate 404 at its corresponding end to slide toward the center of the arc-shaped chamber. The two oppositely positioned cylinders 402 offset the length of each other's fixed ends, allowing the piston plates 404 to completely push the spray agent out of the chamber. This constant volume of spray agent helps form a uniformly thick spray layer on the outside of the pipe.

[0059] In this embodiment, the adsorption structure 5 includes a cylindrical plate and an adsorption strip 501 , a communication port 502 , and a slide groove 503 .

[0060] Specifically, the cylindrical plate matches and fits the inner wall of the storage chamber 401, and a number of adsorption strips 501 are provided on the cylindrical plate. The adsorption strips 501 are porous cotton-like structures. The adsorption strips 501 are extended along the length direction of the pipeline. The interior of the adsorption strips 501 is hollow. The adsorption strips 501 are arranged in a circle on the inner wall of the cylindrical plate along the center of the cylindrical plate.

[0061] When the spray is sprayed into the confined space, spray mist particles are formed, which then adhere evenly to the outer wall of the pipe. During this process, the porous cotton-like structure of the adsorption strip 501 will slowly adsorb some of the mist particles and adsorb the mist particles in the entire confined space, avoiding the accumulation of easily dissipated and harmful spray mist particles in the confined space after the spraying is completed.

[0062] In addition, when the spray layer outside the pipe has not dried yet, the adsorption strip 501 will continue to absorb moisture in the spray layer to accelerate its drying. The hollow interior of the adsorption strip 501 is conducive to storing more moisture and spray particles, while the cotton-like structure outside the hollow will prevent them from leaking out.

[0063] In this embodiment, a slide rod 406 is also connected to the connecting plate 403. The end of the slide rod 406 slides in a chute 503, which is spirally arranged on the outer wall of the cylindrical plate. When the slide rod 406 slides in the chute 503, it drives the cylindrical plate to rotate. A connecting port 502 extends between two adjacent adsorption strips 501 on the cylindrical plate. Multiple chamber outlets 405 are also evenly distributed on the inner side of the arc-shaped chamber formed by the storage cavity 401.

[0064] When the piston plate 404 is located at both ends of the arc-shaped chamber, the communication port 502 and the chamber outlet 405 are not connected, the chamber outlet 405 is closed, and the spraying agent cannot be sprayed out. This is the situation when the spraying agent is not sprayed.

[0065] When the piston plate 404 slides toward the middle of the arc-shaped chamber, the slide rod 406 moves with the piston plate 404, thereby driving the cylindrical plate and the connecting port 502 on the cylindrical plate to rotate, so that the connecting port 502 and the chamber outlet 405 are connected, and the spray agent begins to spray out. This is the situation when the spray agent is sprayed.

[0066] In this embodiment, the spray agent pipeline structure 6 includes a branch pipe 601 , a main pipe 602 , a communication cavity 603 , and a delivery pipe 604 .

[0067] Specifically, one end of multiple branch pipes 601 is connected to an arc-shaped chamber, and the other end of multiple branch pipes 601 is connected to a main pipe 602. Each arc-shaped chamber is matched with a main pipe 602, and all main pipes 602 are connected to an annular connecting chamber 603. The connecting chamber 603 is arranged outside the supporting shell 101. A delivery pipe 604 is arranged on the connecting chamber 603, and the delivery pipe 604 is connected to the spray agent storage tank.

[0068] Thus far, various embodiments of the present invention have been described in detail. To avoid obscuring the concept of the present invention, some details known in the art have been omitted. Based on the above description, those skilled in the art will fully understand how to implement the technical solutions of the present invention.
