[0035] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0038] It should also be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application.

In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.

[0039] Additionally, in the following description, specific details are provided to provide a thorough understanding of the examples, however, one skilled in the art will appreciate that the examples can be practiced without these specific details.

[0040] In view of this, the applicant conducted in-depth research and improvement exploration on the pasting and pressure application of electric heaters, and found that: the existence of pores in the silicone layer, the warping of corners caused by weak adhesion, and other quality defects will cause the local temperature of the heater to be too high, which will in turn cause the heater to fail. In the process of pasting electric heaters with silicone rubber, external force is required to apply pressure to the heater to increase the strength of the bond. The pressure of flat components such as structural plates can be applied by sandbags and other pressure objects. However, for tank components with arc-shaped surfaces, it is difficult to apply pressure to the surface of the heater using traditional methods. Based on the above, the research and design of the pressure application of heaters pasted on this special surface can improve the pass rate and pressure efficiency of the pasting implementation, which has a relatively clear application scenario.

[0041] Based on this, the technical solutions provided by the various embodiments of the present application are described below in conjunction with the accompanying drawings.

[0042] The embodiment of this specification proposes an electric heater pasting pressure device, such as Figure 1 and Figure 2 As shown, the electric heater has a flexible structure, which is attached to the surface of the component to be heated via the flexible structure to heat the component. The electric heater can have a film-like flexible structure or a sheet-like flexible structure. The component to be heated can be a tank 9. The electric heater can be a polyimide film-type electric heater attached to the surface of a spherical tank 9 suitable for use in satellite propulsion systems.

[0043] The pressure device includes a pressure plate 2 and a pressure drive mechanism. The pressure drive mechanism is used to drive the pressure plate 2 to apply pressure to the flexible structure, causing the flexible structure to adhere to the surface of the component to be heated. The pressure surface of the pressure plate 2 is configured to conform to the surface of the component to be heated. The driven pressure plate 2 applies pressure to the flexible structure via the pressure surface, causing the pressure-bonding surface of the flexible structure to adhere to the surface of the component to be heated using its own flexibility. For example, the pressure plate 2 can be driven in a direction perpendicular to the cross-section of the surface to be heated. The surface of the storage tank 9 may include an arcuate surface and / or a flat surface. The arcuate surface may be a circular arc. After the electric heater is adhered to the surface of the component to be heated using single-component vulcanized silicone rubber, further pressure is applied using adhesive tape, and then pressure is applied by the pressure device.

[0044] The present application can solve the problem that it is difficult to apply pressure using sandbags, wrapping belts, etc. after the heater of components with arc-shaped surfaces such as the storage tank 9 is implemented, and the pressure applied using tape is insufficient. It provides an electric heater pressure device with a simple structure, strong targeting, and easy operation and use.

[0045] In one embodiment, Figure 1 and Figure 2As shown, the pressure device also includes an elastic spacer 1; the elastic spacer 1 is a sheet-like structure; the elastic spacer 1 is fixed on the pressure surface in a conformal manner, and the pressure surface applies pressure to the flexible structure by pressing the electric heater through the elastic spacer 1; the pressing surface of the elastic spacer 1 is conformed to the surface to be adhered to the component to be heated.

[0046] In one embodiment, Figure 1 and Figure 2 As shown, the area of ​​the surface of the elastic spacer 1 that is pressed against the electric heater is larger than the area of ​​the pressed surface of the electric heater.

[0047] In one embodiment, Figure 1 and Figure 2 As shown, the thickness of the elastic spacer 1 is greater than the thickness of the electric heater, so that the elastic spacer 1 can be pressed and covered by the electric heater.

[0048] In one embodiment, Figure 1 and Figure 2 As shown, the elastic spacer 1 comprises a rubber pad, bonded to the pressure surface with an adhesive; the pressure surface is shaped like an arc. The elastic spacer 1 contacts the heater and exhibits a certain degree of elasticity, deforming when pressure is applied. The elastic spacer 1 is a rubber pad, one side of which mates well with the spherical surface of the tank 9, and the other side mates well with the curved pressure plate 2. The elastic spacer 1 is slightly larger than the heater to be pressurized, fully covering the heater and bonded to the curved pressure plate 2 with an adhesive.

[0049] In one embodiment, Figure 1 and Figure 2 As shown, the pressure drive mechanism includes a push plate 6 and an elastic member. One end of the elastic member along its own elastic direction abuts against the pressure plate 2, and the other end of the elastic member along its own elastic direction abuts against the push plate 6. The elastic direction of the elastic member is the driven direction of the pressure plate 2, so that the push plate 6 moves to compress the elastic member, and the elastic member uses the elastic restoring force generated by compression to drive the pressure plate 2.

[0050] In one embodiment, Figure 1 and Figure 2 As shown, the pressure drive mechanism also includes multiple guide rods, and the elastic members are arranged in multiple numbers; the multiple guide rods are fixed on the pressure plate 2, the push plate 6 is slidably mounted on the multiple guide rods, and the multiple elastic members are mounted one by one on the multiple guide rods, and are configured such that the guide rods are used for guiding the movement of the push plate 6 and the elastic movement of the elastic members.

[0051] In one embodiment, Figure 1 and Figure 2As shown, the pressure drive mechanism also includes a fixed bracket 7 and a drive rod; the fixed bracket 7 is installed on the parking fixture of the component to be heated, and the end of the guide rod facing away from the pressure plate 2 is fixedly connected to the fixed plate of the fixed bracket 7; the drive rod is movably installed on the fixed plate along the driven direction of the pressure plate 2, and is connected to the push plate 6, and is configured so that the drive rod pushes the push plate 6 to move; the guide rod is a telescopic rod, and the telescopic direction of the guide rod is the driven direction of the pressure plate 2; the guide rod is configured so that the guide rod performs telescopic movement following the elastic movement of the elastic member. One end of the telescopic rod along its own telescopic direction is fixed to the fixed bracket 7, and the other end of the telescopic rod along its own telescopic direction is fixed to the pressure plate 2.

[0052] In one embodiment, Figure 1 and Figure 2 As shown, the parking fixture is provided with a waist-shaped hole. The movable plate of the fixed bracket 7 is mounted on the parking fixture via fasteners. The movable plate is slidably connected to the waist-shaped hole via the fasteners. The movable plate is slidably arranged to adjust the distance between the fixed plate and the surface of the component to be heated. The waist-shaped hole is located on the side closest to the surface of the component to be heated, and the fixed plate and movable plate are fixedly connected. The sliding direction of the movable plate is, for example, along the transverse projection of the driven direction of the pressure plate 2.

[0053] In one embodiment, Figure 1 and Figure 2 As shown, the guide rod includes a fixed sleeve 4 and a movable rod 3. The fixed sleeve 4 is fixedly connected to the fixed plate, and the movable sleeve is fixedly connected to the pressure plate 2. The movable rod 3 is slidably disposed in the fixed sleeve 4 along the driven direction of the pressure plate 2. The elastic member includes a spring 5, whose ends along its elastic direction are flat and press the pressure plate 2 and the push plate 6. The drive rod includes a threaded rod 8, which is threadedly connected to the fixed plate. The bottom of the movable plate has a threaded hole, and the fastener is threadedly connected to the movable plate. The push plate 6 serves as a pressure plate for the spring 5.

[0054] The arc-shaped pressure plate 2 is connected to the movable rod 3 of the telescopic rod, and is displaced under the action of the spring 5, transmitting the elastic force of the spring 5 to the surface of the heater; one side of the arc-shaped pressure plate 2 is an arc surface, and the other side is a plane, and the arc-shaped pressure plate 2 is connected to the movable rod 3 of the telescopic rod; the arc-shaped pressure plate 2 is provided with 6 countersunk screw holes, and the movable rod 3 of the telescopic rod is connected and fixed to the arc-shaped pressure plate 2 by screws.

[0055] The spring 5 is the pressure source. When compressed, it generates pressure, acting on the pressure plate 2. Six springs 5 ​​are inserted into the telescopic rod, with flat ends that are compressed. The movable rod 3 of the telescopic rod is connected to the curved pressure plate 2 and moves synchronously during pressure application. The fixed sleeve 4 of the telescopic rod is connected to the fixed bracket 7 to maintain its position during pressure application. The telescopic rod consists of the movable rod 3 and the fixed sleeve 4. The movable rod 3 is made of solid bar stock, while the fixed sleeve 4 is made of tubing and connected to the fixed bracket 7 with screws.

[0056] The push plate 6 compresses the six springs 5 ​​at the same time; the push plate 6 passes through the fixed sleeve 4 of the telescopic rod and is connected to the threaded rod 8.

[0057] The push plate 6 is provided with 7 through holes, 6 of which are through holes for the telescopic rods, and the middle hole is a connecting hole for the threaded rod 8 and the push plate 6 .

[0058] The fixing bracket 7 is fixed on the tank parking tooling 10, bearing the reaction force of the spring 5; the fixing bracket 7 is fixed on the fixing ring of the tank 9; a threaded hole is opened at the bottom of the fixing bracket 7, and it is fixed to the fixing ring of the tank 9 by screws.

[0059] Rotating the threaded rod 8 drives the push plate 6 to compress the spring 5, changing the amount of compression applied to the spring 5 and thus the amount of applied pressure. One end of the threaded rod 8 is movably connected to the push plate 6, and the other end is threadedly connected to the fixed bracket 7. Rotating the threaded rod 8 causes the push plate 6 to squeeze the spring 5, which in turn transmits pressure to the curved pressure plate 2, ultimately applying pressure to the electric heater. One end of the threaded rod 8 is fixed to the push plate 6 by a nut. The thread radius of the nut is smaller than the center hole diameter of the push plate 6. When the threaded rod 8 rotates, the push plate 6 does not rotate with it.

[0060] like Figure 1 and Figure 2 As shown, after the heater is coated with silicone, it is allowed to stand for the required time and then pasted to the surface of the storage tank 9 to be pasted. The bubbles generated need to be pushed out during the pasting process. 3M paper tape is first used to fit the edge of the heater to the surface of the storage tank 9. At the same time, paper tape is used to apply pressure to the heating plate along the spherical latitude direction. The screws of the pressure device bracket and the storage tank 9 fixing fixture are loosened, and the distance between the pressure device and the storage tank 9 ball is adjusted. After the elastic spacer 1 contacts the heater, the fixing screws of the pressure device bracket are tightened, and then the threaded rod 8 of the pressure device is rotated. After the predetermined number of turns, the elastic spacer 1 is deformed, and the pressure device applies pressure to the heater. After 24 hours, the threaded rod 8 is rotated in the opposite direction to loosen the pressure applied to the heater, loosen the fastening screws of the pressure device and the storage tank 9 fixing fixture, and remove the pressure device from the storage tank 9 fixing fixture.

[0061] The electric heating pressure device of the present application includes an elastic spacer 1, a curved pressure plate 2, a spring 5, a telescopic rod, a push plate 6, a fixed bracket 7, and a threaded rod 8. The heater pressure device of the present application can directly apply pressure to a heater attached to a curved surface. The shape of the pressure plate 2 fits well with the arc surface, and the applied pressure can be effectively transmitted to the heater surface. It can also apply pressure to the edge of the heater, solving problems that are difficult to solve with traditional pressure methods. The amount of applied pressure can be quantified according to the amount of screwing of the threaded rod 8, which is convenient for personnel operation and effectively improves the pass rate of the curved surface heater attachment.

[0062] This application relates to the installation and implementation of a polyimide film-type electric heater. It can solve problems that affect the quality of heater attachment, such as warping of corners, insufficient pressure from paper tape wrapping, and uneven pressure, that occur during the attachment of heaters to the surface of a spherical tank 9 in a satellite propulsion system. By adjusting the expansion and contraction of spring 5, and thereby controlling the pressure applied by the arc-shaped pressure plate 2, pressure is applied to the electric heater. The device applies pressure to the electric heater after it has been attached using single-component vulcanized silicone rubber. The arc-shaped pressure plate 2 and elastic spacer 1 adhere well to the spherical surface, effectively and continuously applying uniform pressure to the edge area of ​​the heater, thus avoiding attachment quality issues caused by inadequate or insufficient pressure.

Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present application should be included in the scope of protection of the present application.
