Description

Technical Field

[0001] The present invention relates to the technical field of compressed air energy storage, and particularly to a compressed air energy storage test tunnel. Background Art

[0002] With the acceleration of the global energy transformation, compressed air energy storage technology, due to its large capacity, long life and environmental protection characteristics, plays an increasingly important role in the field of energy storage. To ensure the stable operation of the compressed air energy storage system, it is crucial to build a safe and efficient dedicated artificial passage to enter the interior of the energy storage hole for maintenance;

[0003] However, there are two major problems in the construction of the artificial passage: one is the great difficulty in pipe processing, especially for large-sized elbows, with a weight exceeding 20 tons, which poses extremely high requirements for processing technology, and it is difficult to guarantee the processing accuracy and quality by traditional methods; the other is the extremely difficult transportation and hoisting of the pipe in the cave. The cave space is limited and the terrain is complex. The overweight and oversized volume of the pipe makes it difficult to implement conventional means, not only with great potential safety hazards, but also seriously affecting the construction efficiency;

[0004] To address these problems, the pipe is designed to be segmented, composed of straight pipes and elbows, which is convenient for segmented transportation to the site and then assembly and welding. However, the complex space environment inside the cave brings great difficulties to the hoisting operation. The hoisting equipment needs to be accurately positioned and adjusted within the limited operation space to accurately align the pipes. This process is time-consuming and laborious, resulting in a slow construction progress. At the same time, the welding operation needs to be manually welded and carried out around the pipe in a circle, further increasing the construction difficulty and time cost. Based on this, the present invention purposefully provides a compressed air energy storage test tunnel that can simplify the process of pipe assembly and welding. Summary of the Invention

[0005] The purpose of the present invention is to provide a compressed air energy storage test tunnel for the deficiencies of the prior art to solve the technical problems in the prior art.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] A compressed air energy storage test tunnel: It includes elbows and straight pipes. Both ends of the elbow are connected to a straight pipe through pipe clamp assemblies. The pipe clamp assemblies are connected to hoisting assemblies. The hoisting assemblies lift the elbows and straight pipes through the pipe clamp assemblies. A linkage assembly is provided on the straight pipe;

[0008] The pipe clamp assembly on the elbow is connected to a first fixing block. A V-shaped groove is formed in the first fixing block. The pipe clamp assembly on the straight pipe is connected to a second fixing block. A rotating rod is rotatably installed in the second fixing block. A V-shaped block is fixedly connected to the rotating rod. The hypotenuse of the V-shaped block is slidably matched with the hypotenuse of the V-shaped groove;

[0009] Two symmetrically arranged sliding plates are slidably mounted on the straight pipe. A plurality of fixing rods are fixedly mounted on each sliding plate, and the plurality of fixing rods form a semi-circle. The fixing rods are slidably connected to the pipe clamp assemblies on the straight pipe. When one sliding plate slides on the straight pipe, the sliding plate drives the other sliding plate to move in the opposite direction through a linkage assembly, and the fixing rods on the two sliding plates are alternately connected to the pipe clamp assemblies on the bent pipe.

[0010] As a further scheme of the present invention: The pipe clamp assembly includes a connection block, a lower receiving plate, an upper receiving plate and a hanging ring. Connection blocks are fixedly connected to both the bent pipe and the straight pipe. The lower receiving plate is slidably mounted on the connection block. The upper receiving plate is slidably clamped with the lower receiving plate. The lower receiving plate is slidably connected to the fixing rod. The upper receiving plate is slidably connected to the fixing rod. The two upper receiving plates and the lower receiving plate respectively clamp and fix the bent pipe and the straight pipe. The hanging ring is fixedly mounted on the top end of the upper receiving plate, and the hanging ring is connected to the hoisting assembly.

[0011] As a further scheme of the present invention: The pipe clamp assembly further includes a trapezoidal groove and a trapezoidal block. The trapezoidal groove is opened on the lower receiving plate. The trapezoidal block is fixedly mounted on the upper receiving plate. The trapezoidal block is slidably engaged with the trapezoidal groove.

[0012] As a further scheme of the present invention: The linkage assembly includes a first rack plate, a second rack plate, a fixing plate, a round rod and a gear. The fixing plate is fixedly mounted on the second fixing block. The first rack plate is fixedly connected to one sliding plate. The second rack plate is fixedly connected to the other sliding plate. The round rod is mounted on the fixing plate. The gear is rotatably mounted on the round rod, and the gear is located between the first rack plate and the second rack plate. Both the first rack plate and the second rack plate are engaged with the gear.

[0013] As a further scheme of the present invention: The round rod is slidably mounted on the fixing plate. A limiting assembly is arranged on the fixing plate. The limiting assembly is connected to the round rod. When the limiting assembly locks the round rod, the position of the round rod is constant. When the limiting assembly unlocks the round rod, the sliding of the round rod will drive the gear away from the first rack plate and the second rack plate.

[0014] As a further scheme of the present invention: The limiting assembly includes a convex block, a groove and a slider. The groove is opened on the fixing plate. The convex block is fixedly mounted on the outer circular surface of the round rod, and the convex block is slidably connected to the groove. The slider is slidably mounted on the fixing plate, and the slider abuts against the convex block.

[0015] As a further scheme of the present invention: A fixing plate is fixedly connected to the outer circular surface of the straight pipe. Extension strips are fixedly connected to both sides of the fixing plate. The sliding plate is slidably mounted on the fixing plate, and the sliding plate is slidably connected to the extension strips.

[0016] As a further solution of the present invention: a card slot is provided on the fixed plate, a card block is slidably engaged in the card slot, and the card block abuts against the sliding plate.

[0017] Beneficial effects of the present invention:

[0018] 1. In the present invention, firstly, the butt ends of the bent pipe and the straight pipe are connected to the pipe clamp assembly, and the pipe clamp assembly is lifted by the lifting assembly, and then the V-shaped block on the rotating rod can fall into the V-shaped groove. The moving direction of the straight pipe can be visualized by the position of the V-shaped block on the V-shaped groove, until the V-shaped block slides to a position that completely matches the V-shaped groove, indicating that the axes of the bent pipe and the straight pipe are completely overlapped, so that it is convenient to align the bent pipe and the straight pipe, and then the pipe clamp assembly on the bent pipe and the pipe clamp assembly on the straight pipe are connected by the fixing rod, so as to enhance the stability of the butt joint of the bent pipe and the straight pipe, and half of the welds of the bent pipe and the straight pipe are always unobstructed, and the exposed welds can be manually welded at this time;

[0019] 2. In the present invention, the lower receiving plate is inserted along the track of the connecting block, and then the upper receiving plate and the lower receiving plate are slidably connected. At this time, the lower receiving plate and the upper receiving plate can fix the bent pipe and the straight pipe by clamping. Finally, the hoisting assembly and the hanging ring are connected to lift the bent pipe and the straight pipe. This is convenient for construction workers to quickly complete the installation at the hoisting site, reduce the installation time, and improve work efficiency. After completing the welding of the bent pipe and the straight pipe, the upper receiving plate and the lower receiving plate can be disassembled in sequence without damage to the components, and can be reused in subsequent similar hoisting and welding work, thereby reducing costs.

[0020] 3. In the present invention, the movement of the sliding plate will drive the first rack plate to move synchronously, and the first rack plate and the second rack plate are both meshed with the gear, so the first rack plate will drive the gear to rotate, and the gear will drive the second rack plate to move in the opposite direction, so that the upper sliding plate will move away from the lower supporting plate, and the lower sliding plate will move closer to the lower supporting plate until it is transformed into the state shown in the figure. In this way, when the bent pipe and the straight pipe are not welded at all, the upper supporting plate on the bent pipe and the upper supporting plate on the straight pipe can be connected by the fixing rod to establish a rigid connection, which can improve the stability of the docking of the bent pipe and the straight pipe during welding.

Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0030] Please refer to Figures 1-6 as shown, the present invention is a compressed air energy storage test tunnel, which includes a bent pipe 1 and a straight pipe 2. Both ends of the bent pipe 1 are connected to a straight pipe 2 through a pipe clamp assembly 3. The pipe clamp assembly 3 is connected to a hoisting assembly. The hoisting assembly hoists the bent pipe 1 and the straight pipe 2 through the pipe clamp assembly 3. A linkage assembly 11 is provided on the straight pipe 2;

[0031] The pipe clamp assembly 3 on the bent pipe 1 is connected to a first fixing block 4. A V-shaped groove 5 is opened on the first fixing block 4. The pipe clamp assembly 3 on the straight pipe 2 is connected to a second fixing block 6. A rotating rod 7 is rotatably installed in the second fixing block 6. A V-shaped block 8 is fixedly connected to the rotating rod 7. The hypotenuse of the V-shaped block 8 is slidably matched with the hypotenuse of the V-shaped groove 5;

[0032] Two symmetrically arranged sliding plates 9 are slidably installed on the straight pipe 2, and multiple fixing rods 10 are fixedly installed on each sliding plate 9. The multiple fixing rods 10 form a semicircle. The fixing rods 10 are slidably connected to the pipe clamp assembly 3 on the straight pipe 2. When one sliding plate 9 slides on the straight pipe 2, the sliding plate 9 drives the other sliding plate 9 to move in the opposite direction through the linkage assembly 11, and the fixing rods 10 on the two sliding plates 9 are alternately connected to the pipe clamp assembly 3 on the bent pipe 1.

[0033] In one case of this embodiment, the lifting assembly includes components such as a crane, a wire rope and a hook. It should be noted that the above components are all prior arts and the present invention does not improve them. Therefore, there is no need to disclose their specific mechanical structure and circuit structure, which does not affect the integrity of the present invention.

[0034] The working principle of the present invention is as follows: first, the two ends of the elbow 1 and one end of the straight pipe 2 are fixed by the pipe clamp assembly 3, and then the hoisting assembly and the pipe clamp assembly 3 are connected, and then the elbow 1 and the straight pipe 2 can be hoisted, and then the pipe opening of the elbow 1 and the pipe opening of the straight pipe 2 need to be aligned, and the specific operation is as follows:

[0035] First, the elbow 1 and the straight pipe 2 are brought close together by the hoisting assembly, and then the rotating rod 7 is manually rotated so that the V-shaped block 8 on the rotating rod 7 can fall into the V-shaped groove 5. If the axis of the pipe opening of the elbow 1 and the pipe opening of the straight pipe 2 do not coincide, the inclined plate of the rotating rod 7 will fall on the hypotenuse of the V-shaped groove 5. When the V-shaped block 8 falls to the right on the V-shaped groove 5, the hoisting assembly controls the straight pipe 2 to move to the left. At this time, the axis of the straight pipe 2 will gradually approach the axis of the elbow 1, and the V-shaped block 8 will also slide on the V-shaped groove 5. In this way, the moving direction of the straight pipe 2 can be visualized through the position of the V-shaped block 8 on the V-shaped groove 5, until the V-shaped block 8 slides to the V-shaped groove 5. The completely matched position, that is, the beveled edges on both sides of the V-shaped block 8 are completely fitted with the beveled edges on both sides of the V-shaped groove 5. At this time, it means that the axes of the bent pipe 1 and the straight pipe 2 are completely overlapped. Then the lifting assembly controls the straight pipe 2 to approach the bent pipe 1. Subsequently, before welding the bent pipe 1 and the straight pipe 2, the two sliding plates 9 are slidably installed on the straight pipe 2, and the fixing rods 10 on the sliding plates 9 will slide through the pipe clamp assembly 3 on the straight pipe 2. When one sliding plate 9 slides on the straight pipe 2, the sliding plate 9 drives the other sliding plate 9 to move in the opposite direction through the linkage assembly 11, so that the fixing rods 10 on the two sliding plates 9 are alternately connected with the pipe clamp assembly 3 on the bent pipe 1, as shown in FIG. Figure 1 and Figure 3In the two states shown, the pipe clip assemblies 3 on the elbow pipe 1 and the straight pipe 2 are connected by the fixing rod 10, so as to enhance the stability of the butt joint between the elbow pipe 1 and the straight pipe 2, and there is always no blockage at half of the welds of the elbow pipe 1 and the straight pipe 2. At this time, workers can perform welding treatment on the exposed welds. After the welding is completed, move the sliding plate 9 to expose the other half of the welds. In this way, the welding treatment of the elbow pipe 1 and the straight pipe 2 is carried out in two times.

[0036] As Figures 1-4 shown, as a preferred embodiment of the present invention, the pipe clip assembly 3 includes a connecting block 301, a lower bearing plate 302, an upper bearing plate 303 and a hanging ring 304. Connecting blocks 301 are fixedly connected to both the elbow pipe 1 and the straight pipe 2. The lower bearing plate 302 is slidably installed on the connecting block 301. The upper bearing plate 303 is slidably clamped with the lower bearing plate 302. The lower bearing plate 302 is slidably connected to the fixing rod 10. The upper bearing plate 303 is slidably connected to the fixing rod 10. The two upper bearing plates 303 and the lower bearing plate 302 respectively clamp and fix the elbow pipe 1 and the straight pipe 2. The hanging ring 304 is fixedly installed at the top of the upper bearing plate 303, and the hanging ring 304 is connected to the hoisting assembly.

[0037] In the actual application of this embodiment, the connecting block 301 is fixedly installed on the elbow pipe 1 and the straight pipe 2. At the beginning, first lift the elbow pipe 1 and the straight pipe 2, then insert the lower bearing plate 302 along the track of the connecting block 301, and then slidably clamp the upper bearing plate 303 and the lower bearing plate 302. At this time, the lower bearing plate 302 and the upper bearing plate 303 can clamp and fix the elbow pipe 1 and the straight pipe 2. Finally, connect the hoisting assembly and the hanging ring 304, and the elbow pipe 1 and the straight pipe 2 can be lifted. In this way, it is convenient for construction workers to quickly complete the installation at the hoisting site, reduce the installation time, improve work efficiency, and after completing the welding work of the elbow pipe 1 and the straight pipe 2, the upper bearing plate 303 and the lower bearing plate 302 can be disassembled in sequence. If the components are not damaged, they can be reused in subsequent similar hoisting and welding work, reducing costs.

[0038] As Figures 1-5 shown, as a preferred embodiment of the present invention, the pipe clip assembly 3 further includes a trapezoidal groove 305 and a trapezoidal block 306. The trapezoidal groove 305 is opened on the lower bearing plate 302. The trapezoidal block 306 is fixedly installed on the upper bearing plate 303. The trapezoidal block 306 is slidably engaged with the trapezoidal groove 305.

[0039] In the actual application of this embodiment, as Figure 5Taking the shown as an example, when assembling the upper bearing plate 303 and the lower bearing plate 302, the trapezoidal block 306 can be inserted along the trapezoidal groove 305 to complete the assembly. In this way, both the assembly and disassembly are very convenient. When lifting, the cooperation between the inclined plate of the trapezoidal block 306 and the inclined side of the trapezoidal groove 305 can also achieve the purpose of lifting the lower bearing plate 302 by only lifting the upper bearing plate 303.

[0040] As Figures 1-6 shown, as a preferred embodiment of the present invention, the linkage assembly 11 includes a first rack plate 1101, a second rack plate 1102, a fixing plate 1103, a round rod 1104 and a gear 1105. The fixing plate 1103 is fixedly installed on the second fixing block 6. The first rack plate 1101 is fixedly connected to a sliding plate 9, and the second rack plate 1102 is fixedly connected to another sliding plate 9. The round rod 1104 is installed on the fixing plate 1103, and the gear 1105 is rotatably installed on the round rod 1104, and the gear 1105 is located between the first rack plate 1101 and the second rack plate 1102. Both the first rack plate 1101 and the second rack plate 1102 are engaged with the gear 1105.

[0041] In actual application of this embodiment, as Figure 1 shown, when moving the upper sliding plate 9, the movement of the sliding plate 9 will drive the first rack plate 1101 to move synchronously. Since both the first rack plate 1101 and the second rack plate 1102 are engaged with the gear 1105, the first rack plate 1101 will drive the gear 1105 to rotate, and the gear 1105 will drive the second rack plate 1102 to move in the opposite direction. In this way, the upper sliding plate 9 moves away from the lower bearing plate 302, and the lower sliding plate 9 will move closer to the lower bearing plate 302 until it is transformed into the state as Figure 3 shown. In this way, when the bent pipe 1 and the straight pipe 2 are not welded at all, the bearing plate 303 of the bent pipe 1 and the upper bearing plate 303 on the straight pipe 2 can be connected by the fixing rod 10 to establish a rigid connection, which can improve the docking stability of the bent pipe 1 and the straight pipe 2 during welding.

[0042] As Figures 1-6 shown, as a preferred embodiment of the present invention, the round rod 1104 is slidably installed on the fixing plate 1103, and a limiting assembly 12 is arranged on the fixing plate 1103. The limiting assembly 12 is connected to the round rod 1104. When the limiting assembly 12 locks the round rod 1104, the position of the round rod 1104 is constant. When the limiting assembly 12 unlocks the round rod 1104, the sliding of the round rod 1104 will drive the gear 1105 to move away from the first rack plate 1101 and the second rack plate 1102.

[0043] In actual application of this embodiment, through the design of the round rod 1104 being slidably installed on the fixed plate 1103, when the limiting component 12 unlocks the round rod 1104, the sliding of the round rod 1104 will drive the gear 1105 away from the first rack plate 1101 and the second rack plate 1102. At this time, the two sliding plates 9 can be removed from the straight pipe 2. Similarly, during installation, first slide the round rod 1104 to a position where the gear 1105 is away from the first rack plate 1101 and the second rack plate 1102, so that the two sliding plates 9 can be installed on the straight pipe 2. In this way, the two sliding plates 9 also become a detachable design, further reducing the difficulty of building the overall test hole.

[0044] As Figures 1-6 shown, as a preferred embodiment of the present invention, the limiting component 12 includes a convex block 1201, a groove 1202, and a slider 1203. The groove 1202 is opened on the fixed plate 1103. The convex block 1201 is fixedly installed on the outer cylindrical surface of the round rod 1104, and the convex block 1201 is slidably connected to the groove 1202. The slider 1203 is slidably installed on the fixed plate 1103, and the slider 1203 abuts against the convex block 1201.

[0045] In actual application of this embodiment, after the two sliding plates 9 are both installed on the straight pipe 2, as Figure 3 shown as an example, make the first rack plate 1101 and the second rack plate 1102 present a staggered state. At this time, rotate the gear 1105 so that the gear 1105 can mesh with the tooth blocks of the first rack plate 1101 and the second rack plate 1102. Then manually push the round rod 1104 so that the convex block 1201 is inserted into the groove 1202. In this way, the rotation of the round rod 1104 can be blocked. Then manually slide the slider 1203 so that it abuts against the convex block 1201. In this way, when the gear 1105 rotates, it can be avoided that the round rod 1104 moves, and further, the problem that the convex block 1201 moves out of the groove 1202 and the gear 1105 disengages from between the first rack plate 1101 and the second rack plate 1102 is avoided.

[0046] As Figures 1-4 shown, as a preferred embodiment of the present invention, a fixed platform 13 is fixedly connected to the outer cylindrical surface of the straight pipe 2. Extension strips 14 are fixedly connected to both sides of the fixed platform 13. The sliding plate 9 is slidably installed on the fixed platform 13, and the sliding plate 9 is slidably connected to the extension strips 14.

[0047] In actual application of this embodiment, through the arrangement of the fixed platform 13 and the extension strips 14, the sliding plate 9 can be inserted from one end of the fixed platform 13. For the lower sliding plate 9, the sliding connection relationship between the extension strips 14 and the sliding plate 9 can prevent the sliding plate 9 from falling under the action of gravity, ensuring that the sliding plate 9 can move along a predetermined track.

[0048] AsFigures 1-4 As shown in the figure, as a preferred embodiment of the present invention, a clamping groove 15 is formed on the fixed table 13, a clamping block 16 is slidably clamped in the clamping groove 15, and the clamping block 16 abuts against the sliding plate 9.

[0049] In actual application of this embodiment, after the sliding plate 9 is installed on the straight pipe 2, the clamping block 16 can be clamped into the clamping groove 15. Then, when the sliding plate 9 is moved away from the lower receiving plate 302 or the upper receiving plate 303, it can be directly moved to the place blocked by the clamping block 16, without the need to pay attention to whether the fixing rod 10 is completely inserted into the lower receiving plate 302 or the upper receiving plate 303 on the elbow pipe 1, which is more convenient for workers to operate.

[0050] One embodiment of the present invention has been described in detail above, but the content described is only the preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the present invention application should still fall within the scope covered by the patent of the present invention.
