DETAILED DESCRIPTION

[0029] Example 1

[0030] See also Figure 1 and Figure 2 A temperature control device for epoxy material construction includes a heat preservation greenhouse 201, which is installed in the epoxy material construction area.

[0031] The low-temperature epoxy material (epoxy material) used is PHILLYMASTIC TG-7B low-temperature epoxy material produced by Yigong Polymer (Wujiang) Co., Ltd.

[0032] The temperature control system is arranged in the epoxy material construction area (inside the insulation greenhouse), and includes at least one temperature sensor 202 , at least one heating fan 203 and a control module 204 . The temperature sensor 202 and the heating fan 203 are both connected to the control module 204 .

[0033] When the temperature detected by the temperature sensor is less than 13°C, the control module controls the heating fan to work; when the temperature detected by the temperature sensor is greater than 35°C, the control module controls the heating fan to stop working.

[0034] The present invention can provide a suitable temperature environment (facilitating construction in a low-temperature environment) for the installation process of the fuel tank pressure-bearing wood (combined with epoxy material, the fuel tank bottom is painted with epoxy material, the pressure-bearing wood is installed to the fuel tank bottom where the epoxy material is painted, and the jacking of the pressure-bearing wood can be achieved by a scissor lift mechanism, etc., and reference can be made to the existing technology), thereby improving the construction effect.

[0035] In an embodiment, the heat preservation greenhouse 201 includes columns 201a distributed at four corners, and lateral support portions (not shown) are provided between adjacent columns 201a. The lateral support portions and the columns constitute a support frame. The lateral support portions can be designed as needed, and reference can also be made to the prior art. A top cover 201b is provided on the top of the columns 201a, and side panels 201c are provided on the sides of the columns 201a. An opening and closing door is provided at least on one side of the side panels. The opening and closing door facilitates the entry and exit of personnel and materials (large-sized parts such as fuel tanks are pre-placed in the construction area. After the heat preservation greenhouse is manufactured and hoisted to the construction area, the fuel tanks and other components pre-placed in the construction area will be covered inside). At the same time, after closing, the internal space is relatively sealed to facilitate heat preservation. The heat preservation greenhouse covers the epoxy material construction area inside, facilitating heat preservation operations and reducing the impact of the external environment on the epoxy material construction area. In particular, a lifting ring can be provided on the top of each column (not shown, the bottom of the lifting ring passes through the top cover and connects to the column). The insulation greenhouse can be easily hoisted (to or from the epoxy material construction area) through four hoisting rings, which is beneficial to construction.

[0036] In this embodiment, the temperature sensor 202 is mounted on a tabletop 205 with four legs. The top of the tabletop 205 is 20-30 cm above the bottom of the fuel tank 100. The control module 204 is also mounted on the tabletop 205. The joint between the pressure-bearing wood and the fuel tank is at a certain height above the ground (the fuel tank is suspended by a bracket). The characteristics of hot air can easily cause the upper space to have a higher temperature and the lower space to have a lower temperature. This design improves the accuracy of overall space temperature measurement (especially the temperature measurement at the height where the pressure-bearing wood and the fuel tank meet).

[0037] In this embodiment, two heating fans (which do not affect each other's operation) and two temperature sensors are installed at each fuel tank 100. When the temperature value detected by any temperature sensor is less than 13°C, the control module controls the heating fan to operate. When the temperature value detected by any temperature sensor is greater than 35°C, the control module controls the heating fan to stop operating. The reasonable arrangement of the heating fans and the number of temperature sensors can improve the temperature control effect. 13-35°C is the ideal temperature for epoxy material construction. If the temperature value detected by any temperature sensor deviates from this range, the temperature control device will be activated (started or stopped), improving system agility. The arrangement of multiple temperature sensors can also improve the reliability of the device.

[0038] Example 2

[0039] The basic scheme is the same as Example 1, except that Figure 3-Figure 9The heating fan is installed (placed on the disc of the wind sweeping mechanism, which will be described below) at the wind sweeping mechanism 206. The wind sweeping mechanism 206 has a base 206a with a U-shaped cross section. A mounting platform 206b is provided in the base 206a. A bearing 206c is installed on the mounting platform 206b. A vertical shaft 206d is installed on the bearing 206c. A shaft gear 206e is provided on the vertical shaft 206d. The shaft gear 206e is driven by a motor. The motor is installed on the mounting platform. The motor can rotate forward and reverse (the forward rotation angle and the reverse rotation angle can be adjusted according to actual needs). Determine, the motor can refer to the existing technology), a disk 206f (can be made of stainless steel or other materials) is set at the top of the vertical shaft 206d, a plurality of hemispherical recesses are arranged at equal intervals in the circumferential direction on the top of the base 206a (there are three hemispherical recesses in the embodiment), and stainless steel balls 206g are arranged in the recesses (correspondingly, there are three balls in the embodiment), and the lower side of the disk is matched with the balls (the outer side of the disk is supported by the balls, and at the same time, during the rotation process, the balls can move in the hemispherical recesses to assist the rotation of the disk, and lubricating oil is added to the hemispherical recesses as needed).

[0040] The disk 206g and the vertical axis 206d are connected by several connecting members (two connecting members in the embodiment, one on the left side and one on the right side of the vertical axis), and the connecting members have a first rod 206j located on the lower side of the disk, and several oblique limiting bodies 206k are circumferentially arranged at the bottom of the first rod 206j (the oblique limiting bodies are made of stainless steel material, are in sheet shape, and are arranged at equal intervals at the bottom of the first rod 206j. The number can be three, four, five, or more); a first plate 206l is arranged at the top of the vertical axis 206d, and a first plate through hole is provided on the first plate 206l; after the first rod 206j and the oblique limiting body 206k pass through the first plate through hole, the oblique limiting body 206k is expanded to limit; wherein, a plane structure 206p is provided on one side of the vertical axis 206d, and a structural notch 206q is provided in the middle of the disk 206f.

[0041] The disc is placed on top of the base, with the structural notch aligned with the vertical axis (the plane structure of the vertical axis faces backward, the structural notch of the disc faces backward, and with the vertical projection as a reference, the straight line in front of the structural notch coincides with the plane structure of the vertical axis. At this time, the structural notch is aligned with the vertical axis, the first rod on the left is aligned with the through-hole of the first plate, and the first rod on the right is aligned with the through-hole of the first plate). The disc is lowered, and the disc is supported by the ball. The first rod is inserted into the corresponding (directly below) through-hole of the first plate. The oblique limiting body passes into the through-hole of the first plate and folds. After pressing the middle area of ​​the disc, the area is deformed to a certain extent, so that the oblique limiting body can pass through the through-hole of the first plate (when the disc is supported by the ball, the top part of the oblique limiting body is still placed in the through-hole of the first plate). After passing through, it is unfolded and the oblique limiting body is limited (at this time the middle area of ​​the disc is not forced to reset). After installation, the disc and the vertical axis are fixed, and the ball is assisted in limiting. The fixing method of the connecting piece avoids the adverse effect on the installation of the disc caused by the free rotation of the vertical shaft, realizes a better connection between the disc and the vertical shaft, and limits the position of the ball part.

[0042] Due to the existence of the vertical axis plane, lubricating oil can be added through the structural notch, and the lubricating oil can flow downward along the vertical axis plane to the bearing for lubrication (there is an oil groove on the base below the bearing, the oil groove can accumulate lubricating oil, and the accumulated lubricating oil lubricates the bearing), which is conducive to maintenance.

[0043] The motor that can rotate forward and reverse drives the gear shaft. When the motor rotates forward, the disc rotates to one side at a certain angle (in degrees). Figure 7 For example, the disc rotates 90 degrees clockwise, and the specific angle can be set as needed). After it reaches the position, the motor stops and then rotates in the opposite direction, so that the disc rotates a certain angle toward the other side (with Figure 7 For example, the disc rotates 90 degrees counterclockwise (the specific angle can be set as needed), stops when in position, and repeats this process. This allows the heating fan to sweep air, improving the heating effect of the space (area) and enhancing the construction effect. It also improves the heating effect and applicability of ordinary industrial heating fans (which do not have a sweeping function).

[0044] Unless otherwise specified, directions such as front, back, left and right in the embodiments shall be based on the arrows in the accompanying drawings.

[0045] In the embodiment, an outer convex ring 206h and an inner convex ring 206i are respectively provided on the outer side and the inner side of the top of the base 206a, the top heights of the outer convex ring 206h and the inner convex ring 206i are the same and the top height of the outer convex ring 206h is smaller than the top height of the bead 206g, and a top convex ring 206m (the whole is an annular body) is provided on the outer periphery of the bottom of the disc 206f, the top convex ring 206m and the outer convex ring 206h cooperate (the top convex ring can be inserted into the outer convex ring), and a left air hole 206n is provided on the left part of the top convex ring 206m (the left half of the top convex ring), and the entrance of the left air hole 206n faces the left rear, and a right air hole 206o is provided on the right part of the top convex ring 206m (the right half of the top convex ring), and the entrance of the right air hole 206o faces the right rear.

[0046] There is a possibility of lubricating oil overflowing in the hemispherical concave part, and there is a possibility of dripping after the contact point between the disc and the ball contacts a large amount of lubricating oil. A space is formed between the two convex rings to prevent the lubricating oil placed on the top of the base from overflowing and / or dripping and affecting the surroundings (such as safety hazards and the risk of contaminating components). The top convex ring and the outer convex ring cooperate to reduce or prevent external foreign matter from entering the air sweeping mechanism from between the disc and the top of the base and causing adverse effects (affecting the operation of the internal structure). At the same time, the air holes on the left and right sides of the top convex ring can achieve ventilation, which is beneficial to the heat dissipation of the components (such as motors) in the air sweeping mechanism. Figure 7 When the disc rotates clockwise, the air holes on the left side have better air intake effect, and when the disc rotates counterclockwise, the air holes on the right side have better air intake effect, and the ventilation effect is better. Because the top convex ring is inserted into the outer convex ring, the disc can be laterally limited to prevent lateral impact and damage to the connecting parts.

[0047] Example 3

[0048] The basic scheme is the same as that of Example 2, except that the top height of the vertical axis 206d is greater than the top height of the base and less than the top height of the ball. This design prevents damage caused by large deformation during installation of the disc and is close to the structural notch, making alignment easier.

[0049] The outer diameter of the shaft gear is larger than the outer diameter of the bearing. The shaft gear can provide a certain degree of protection for the bearing.

[0050] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions that fall within the principles of the present invention fall within the scope of protection of the present invention. For those skilled in the art, any improvements made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
