Description

Technical Field

[0001] This utility model relates to the field of coating device technology, specifically a thermally controlled high-efficiency coating device. Background Technology

[0002] Thermal control systems are crucial components of complex systems such as spacecraft and power plants. Their primary task is to control the thermal parameters of equipment, such as temperature, temperature difference, and humidity, to meet overall design requirements. They ensure stable operation of equipment through various thermal control devices and components, such as thermal control coatings, heat pipes, and multi-layer insulation assemblies.

[0003] However, there are drawbacks in the existing technology for applying thermal control coatings. After each layer is applied, the coating roller needs to be dipped into the storage tank again to replenish the coating before applying the next layer. This results in low overall work efficiency, and the time spent dipping the coating in affects the overall work efficiency. Therefore, an improved thermal control coating device is needed to address this problem. Utility Model Content

[0004] The purpose of this invention is to provide a thermally controlled, high-efficiency coating device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency thermal control coating device, comprising a handle, an upper end of which is provided with a coating mechanism for applying a heat-insulating coating, the coating mechanism comprising a connecting pipe, a connecting roller, and brush bristles, the upper end of which is fixedly provided with a connecting pipe, the connecting roller being movably disposed on one side of the connecting pipe via a bearing, the outer surface of which is uniformly provided with a plurality of brush bristles, and the connecting pipe being provided with a feeding mechanism for replenishing coating to the connecting roller, the feeding mechanism comprising a connecting rod, a piston, a first one-way valve, a second one-way valve, and a handle, the connecting rod being movably inserted inside the connecting pipe, the piston being fixedly provided at one end of the connecting rod, the first one-way valve being fixedly provided at the lower end of the connecting pipe, and the second one-way valve being fixedly provided on one side of the connecting pipe.

[0006] Preferably, a first spring is sleeved inside the connecting tube on the outer surface of the connecting rod. The first spring can automatically push the connecting rod and the piston to reset, so that the piston can automatically move towards the direction of the second one-way valve.

[0007] Preferably, both the first and second check valves have a sealing ball that is movably engaged inside. A second spring is provided on one side of the sealing ball inside both the first and second check valves, and the sealing ball can be automatically pushed by the second spring to perform the function of a sealing element.

[0008] Preferably, an extension hose is fixedly provided at the lower end of the first one-way valve. The first one-way valve is open from the extension hose to the inside of the connecting pipe, and the second one-way valve is open from the connecting pipe to the connecting roller. The flow direction of the heat insulation coating can be restricted by the first one-way valve and the second one-way valve, so that the coating inside the extension hose can be replenished to the inside of the connecting pipe, while the coating inside the connecting pipe can only be replenished to the inside of the connecting roller.

[0009] Preferably, the handle surface has a slot, and a locking block is fixedly installed at one end of the connecting rod. The locking block is movably engaged inside the slot. When using this device, by holding the handle and pressing the handle, the handle can be rotated around the pivot. At this time, the slot can drive the locking block, connecting rod, and piston to move away from the second one-way valve. This creates a negative pressure inside the connecting pipe. Subsequently, the heat insulation coating can be drawn in through the first one-way valve and the extension hose, ultimately allowing the heat insulation coating to be drawn into the connecting pipe.

[0010] Preferably, the connecting roller has a through groove inside, which allows the heat insulation coating inside the connecting roller to flow out to the outside of the connecting roller. Then the coating comes into contact with the brush bristles. The operator then holds the handle and applies the heat insulation coating by using the connecting roller and the brush bristles. At this time, the coating application can be carried out continuously by simply adding coating to the inside of the connecting roller.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model allows for easy and quick replenishment of paint into the connecting roller by pressing the handle a few times before the paint level is insufficient. This enables continuous application of the heat-insulating coating, reducing the time wasted on dipping the brush in paint and thus greatly improving the coating application efficiency of this device.

[0013] 2. This utility model is easy to operate. The handle and connecting roller make it easy to apply paint while pressing the handle to replenish the paint. This ease of use makes it convenient to promote and use. Attached Figure Description

[0020] 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.

[0021] Please see Figure 1-5 This utility model provides a technical solution: a high-efficiency coating device for thermal control construction, including a handle 1. The upper end of the handle 1 is provided with a coating mechanism for applying a heat-insulating coating. The coating mechanism includes a connecting pipe 2, a connecting roller 3, and brush bristles 4. The connecting pipe 2 is fixedly provided at the upper end of the handle 1. The connecting roller 3 is movably provided on one side of the surface of the connecting pipe 2 through a bearing. A plurality of brush bristles 4 are uniformly fixedly provided on the outer surface of the connecting roller 3. The connecting pipe 2 is provided with a feeding mechanism for replenishing the coating inside the connecting roller 3. The feeding mechanism includes a connecting rod 5, a piston 6, a first one-way valve 7, a second one-way valve 8, and a handle 9. The connecting rod 5 is movably inserted inside the connecting pipe 2. The piston 6 is fixedly provided at one end of the connecting rod 5. The first one-way valve 7 is fixedly provided at the lower end of the connecting pipe 2. The second one-way valve 8 is fixedly provided on one side of the surface of the connecting pipe 2.

[0022] The connecting pipe 2 has a first spring 10 sleeved on the outer surface of the connecting rod 5. The first spring 10 can automatically push the connecting rod 5 and the piston 6 to reset, so that the piston 6 can automatically move towards the second one-way valve 8.

[0023] Both the first one-way valve 7 and the second one-way valve 8 have a sealing ball 11 that is movably engaged inside. A second spring 12 is provided on one side of the sealing ball 11 inside the first one-way valve 7 and the second one-way valve 8. The second spring 12 can automatically push the sealing ball 11 to play the role of a sealing element.

[0024] An extension hose 13 is fixedly installed at the lower end of the first one-way valve 7. The first one-way valve 7 is connected to the inside of the connecting pipe 2 through the extension hose 13, and the second one-way valve 8 is connected to the connecting roller 3 through the connecting pipe 2. The flow direction of the heat insulation coating can be restricted by the first one-way valve 7 and the second one-way valve 8, so that the coating inside the extension hose 13 can be replenished into the inside of the connecting pipe 2, while the coating inside the connecting pipe 2 can only be replenished into the inside of the connecting roller 3.

[0025] The handle 9 has a slot 14 on its surface, and a locking block 15 is fixedly installed at one end of the connecting rod 5. The locking block 15 is movably engaged inside the slot 14. When using this device, by holding the handle 1 and pressing the handle 9, the handle 9 can rotate around the pivot. At this time, the slot 14 can drive the locking block 15, the connecting rod 5, and the piston 6 to move away from the second one-way valve 8. This creates a negative pressure inside the connecting pipe 2. Subsequently, the heat insulation coating can be drawn in through the first one-way valve 7 and the extension hose 13, and finally the heat insulation coating is drawn into the connecting pipe 2.

[0026] The connecting roller 3 has a through groove 16 inside, through which the heat insulation coating inside the connecting roller 3 can flow out to the outside of the connecting roller 3. Then the coating comes into contact with the brush bristles 4. Then the operator holds the handle 1 and applies the heat insulation coating through the connecting roller 3 and the brush bristles 4. At this time, the coating application can be carried out continuously by simply adding coating to the inside of the connecting roller 3.

[0027] Working principle: When using this device, the extension hose 13 can be directly inserted into the storage tank of the heat insulation coating. Then, the operator holds the handle 1 and presses the handle 9, causing the handle 9 to rotate around the pivot. At this time, the locking slot 14 drives the locking block 15, connecting rod 5, and piston 6 to move away from the second one-way valve 8. This creates a negative pressure inside the connecting pipe 2. Subsequently, the heat insulation coating is drawn in through the first one-way valve 7 and the extension hose 13, and finally, the heat insulation coating is drawn into the connecting pipe 2. Then, the operator releases the handle 9. At this time, under the action of the first spring 10, the connecting rod 5 and piston 6 can be pushed towards the second one-way valve 8. When valve 8 is reset, the heat insulation coating inside the connecting pipe 2 is pushed through the second one-way valve 8 into the connecting sleeve. The coating then flows out through the channel 16 to the outside of the connecting roller 3, where it comes into contact with the brush bristles 4. The operator then holds the handle 1 and applies the heat insulation coating through the connecting roller 3 and the brush bristles 4. Before the amount of coating is insufficient, pressing the handle 9 a few times will replenish the coating inside the connecting roller 3. This allows for convenient and quick replenishment of coating to the brush bristles 4, enabling uninterrupted application of the heat insulation coating. This reduces the time wasted on dipping the coating in the process and greatly improves the coating application efficiency of this device.

[0028] Furthermore, this device is easy to operate. The coating work can be easily carried out by holding the lever 1 and connecting the roller 3, and the coating can be replenished by simply pressing the handle 9. This ease of use makes it convenient for widespread adoption.
