Description

Technical Field

[0001] This utility model relates to the field of valve control box technology, specifically a quick-opening structure for a valve control box used in LNG storage tanks. Background Technology

[0002] LNG storage tanks (liquefied natural gas storage tanks) are specialized equipment used to store liquefied natural gas (LNG). Some vehicle-mounted LNG storage tanks have a valve control box at the rear of the tank. By concentrating multiple valves inside the control box, it is easier to operate the valves centrally. The control box also provides some protection for the valves, preventing them from being exposed and reducing the impact of external factors on the valves during vehicle operation. Currently, the valve control box is generally located at the tank position and above the vehicle body, meaning that the bottom of the control box is mostly at the level of a person's torso, resulting in a relatively high overall height. Furthermore, most control boxes have a double-door structure, with a width equivalent to the width of the vehicle body, resulting in a large overall door area. When the control box needs to be fully opened, there must be a large unobstructed space around it; otherwise, the door may be blocked and unable to be fully opened, affecting the convenience of opening the door and causing inconvenience. In addition, most existing control boxes are made of cut metal sheets, and most of them lack internal auxiliary support, resulting in weak impact resistance of the door panel. Utility Model Content

[0003] The purpose of this utility model is to provide a quick-opening structure for a valve operating box for LNG storage tanks, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A quick-opening structure for a valve operating box of an LNG storage tank includes:

[0006] The enclosure comprises a box body, multiple door panels capable of closing the box opening, and a protective mechanism to enhance the impact resistance of the door panels. The box body has a one-sided opening structure, with multiple door panels arranged vertically in sequence. A connecting plate is provided between each pair of adjacent door panels, and each connecting plate is rotatably connected to the side walls of the two adjacent door panels on opposite sides. The top surface of the uppermost door panel is rotatably connected to the inner top surface of the box body. The protective mechanism is located inside the box body and includes two slide rails, which are fixedly connected to the inner top and inner bottom surfaces of the box body, respectively. Multiple sliding plates are slidably engaged between the two slide rails.

[0007] Furthermore, each door panel has a sliding groove on one side, each sliding groove has a rectangular notch at one end, each sliding plate has multiple locking blocks fixedly connected to one side, each sliding plate has multiple locking blocks corresponding to multiple sliding grooves, and each sliding plate has multiple locking blocks slidably engaged inside the corresponding sliding groove.

[0008] Furthermore, the bottom door panel has circular holes on both sides, and each of the two circular holes has a slidably fitted insert rod inside. The box body has insertion holes on both sides, and the two insert rods are movably inserted into the two insertion holes respectively. The bottom surface of the bottom door panel has two connecting rings fixedly connected, and each connecting ring is fixedly connected to the adjacent insert rod with a spring.

[0009] Furthermore, each insertion rod has a guide rod fixedly connected to one end, and each guide rod is slidably sleeved inside the adjacent connecting ring.

[0010] Furthermore, the box body has sleeve holes on both sides, and a winding reel is rotatably fitted inside each sleeve hole. A winding rod is fixedly connected to the inner wall of each winding reel. A pull rope is fixedly connected to the middle of the slide at one end, and the two ends of the pull rope are fixedly wound with the two winding rods respectively. Connecting ropes are fixedly connected between two adjacent slides and between the slide at the other end and the adjacent side wall of the box body. Internal threaded rings are fixedly connected to both sides of the box body. A screw is screwed into the inside of each internal threaded ring. A clamping plate is rotatably connected to the top of each screw. Multiple grooves are opened on the outer wall of each winding reel. Multiple protrusions are fixedly connected to the inner arc surface of each clamping plate. The protrusions are movably engaged in the interior of adjacent grooves.

[0011] Furthermore, a hook is fixedly connected to the bottom surface of the bottom door panel, a square tube is fixedly connected to one side of the box body, and a top rod is provided inside the square tube.

[0012] Furthermore, a collar is fixedly sleeved on the outer wall of the top rod, and rubber plugs are movably engaged on both sides of the square tube.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By using the L-shaped rod on the top rod to hook the hook ring, and then pushing the top rod upwards, multiple door panels can be flipped up, making it easier to open the cabinet. The top rod can be inserted into the positioning hole to support multiple flipped door panels. When the cabinet is closed, the door panels can be positioned by inserting two rods into the insertion holes on the cabinet. Then, rotating the reel to wind up the pull rope will move a slide plate, causing one slide plate to pull multiple slide plates open through the connecting rope. The locking blocks on the multiple slide plates will lock into the sliding grooves on the door panels to provide auxiliary support for the door panels and improve their impact resistance.

Detailed Implementation

[0022] 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.

[0023] Please see Figure 1-6 In this embodiment of the present invention, a quick-opening structure for a valve operating box of an LNG storage tank includes:

[0024] The enclosure 100 comprises a box body 100, multiple door panels 200 capable of closing the opening of the box body 100, and a protective mechanism 400 capable of improving the impact resistance of the door panels 200. The box body 100 has a one-sided opening structure, and multiple door panels 200 are arranged vertically in sequence. A connecting plate 210 is provided between two adjacent door panels 200. Each connecting plate 210 is rotatably connected to the side walls of the two adjacent door panels 200 on opposite sides. The top surface of the uppermost door panel 200 is rotatably connected to the inner top surface of the box body 100. The protective mechanism 400 is located inside the box body 100. The protective mechanism 400 includes two slide rails 410, and the two slide rails 410 are fixedly connected to the inner top surface and inner bottom surface of the box body 100, respectively. Multiple sliding plates 420 are slidably engaged between the two slide rails 410.

[0025] Specifically, the housing 100 is an existing valve control box. Multiple door panels 200 are used to close the opening of the housing 100. When the housing 100 is opened, only the top door panel 200 is connected to the housing 100, while the other door panels 200 can rotate freely. This allows the other door panels 200 and the connecting plate 210 to be flipped up, thereby opening the housing 100. This reduces the space required to open the housing 100 and makes it easier for users to operate. Furthermore, when the housing 100 is closed and the multiple door panels 200 hang down naturally, multiple sliding plates 420 can be slid to support the door panels 200, thereby improving the impact resistance of the door panels 200.

[0026] Example 1

[0027] like Figure 1-4 As shown, in this embodiment, each door panel 200 has a sliding groove on one side, and each sliding groove has a rectangular notch at one end. Each sliding plate 420 has multiple locking blocks fixedly connected to one side. The multiple locking blocks on each sliding plate 420 correspond one-to-one with the multiple sliding grooves. The multiple locking blocks on each sliding plate 420 are slidably engaged in the corresponding sliding groove. The bottom door panel 200 has circular holes on both sides, and each of the two circular holes has a slidably fitted insert rod 220 inside. The box body 100 has insertion holes on both sides, and each of the two insert rods 220 is movably inserted into the two insertion holes. The bottom surface of the bottom door panel 200 has two connecting rings 230 fixedly connected. Each connecting ring 230 is fixedly connected to an adjacent insert rod 220. Each insert rod 220 has a guide rod 221 fixedly connected to one end, and each guide rod 221 is slidably fitted in the adjacent connecting ring 230.

[0028] In this embodiment, when the box 100 is closed, the multiple door panels 200 hang naturally and remain parallel to each other. At this time, the two insert rods 220 on the bottom door panel 200 can be moved to align with the insertion holes, and then the insert rods 220 can be released, so that the insert rods 220 are driven by the reset force of the adjacent springs and locked into the adjacent insertion holes, thereby keeping the multiple door panels 200 fixed. The insert rods 220 can be limited by sliding inside the connecting ring 230 through the guide rod 221 to prevent the insert rods 220 from shifting when moved. When the box 100 is closed, the multiple sliding plates 420 can be slid to make the locking blocks on the sliding plates 420 lock into the adjacent slide grooves, further fixing the door panels 200. When the box 100 is opened, the sliding plates 420 can be slid to concentrate the sliding plates 420 at the rectangular notch of the slide groove, so that when the door panels 200 are flipped up and the box 100 is opened, the locking blocks can naturally disengage from the slide grooves at the rectangular notch.

[0029] like Figure 1 and Figure 3-6As shown, in this embodiment, the housing 100 has sleeve holes on both sides, and a winding reel 430 is rotatably sleeved inside each of the two sleeve holes. A winding rod is fixedly connected to one inner wall of each winding reel 430. A pull rope 431 is fixedly connected to the middle of the slide plate 420 at one end, and the two ends of the pull rope 431 are fixedly wound with the two winding rods respectively. A connecting rope 421 is fixedly connected between two adjacent slide plates 420 and between the slide plate 420 at the other end and the side wall of the adjacent housing 100. An internal threaded ring 440 is fixedly connected to both sides of the housing 100. A screw is screwed into the interior of each internal threaded ring 440. A clamping plate 441 is rotatably connected to the top of each screw. Multiple grooves are opened on the outer wall of each winding reel 430. Multiple protrusions are fixedly connected to the inner arc surface of each clamping plate 441. The protrusions are movably clamped into the interior of adjacent grooves.

[0030] In practice, each pair of adjacent slides 420 is connected to a connecting rope 421, and the slide 420 at one end of the multiple slides 420 is also connected to the side wall of the adjacent box 100 by a connecting rope 421. By rotating any reel 430 to wind up the pull rope 431, the pull rope 431 can drive the slide 420 at one end of the multiple slides 420 to move. This slide 420 pulls other slides 420 through the connecting rope 421 to spread out and support the door panel 200, or it can make the slide 420 abut against other slides 420 and gather at the rectangular notch. This makes it easy for users to adjust the position of the slide 420 outside the box 100. Users can also fix the reel 430 by rotating the screw so that the protrusion on the clamping plate 441 can be inserted into the groove on the adjacent reel 430, thereby fixing the position of the pull rope 431. When users climb the box 100, they can hold the fixed pull rope 431 to assist in climbing.

[0031] Example 2

[0032] Based on Embodiment 1, a top rod 310 is provided to facilitate users to lift the door panel 200.

[0033] like Figure 1 and Figure 6 As shown, in this embodiment, a hook 201 is fixedly connected to the bottom surface of the bottom door panel 200, a square tube 300 is fixedly connected to one side of the box body 100, and a top rod 310 is provided inside the square tube 300. An L-shaped rod is fixedly connected to the outer wall of the top rod 310. A positioning hole is opened on the top surface of the square tube 300, and the top rod 310 is movably inserted into the positioning hole. A collar 311 is fixedly sleeved on the outer wall of the top rod 310, and rubber plugs 320 are movably engaged on both sides of the square tube 300.

[0034] In practice, when it is necessary to open the box 100, the top rod 310 can be pulled out of the square tube 300, and then the L-shaped rod on the top rod 310 can be used to lock the hook ring 201. The top rod 310 can then push the door panel 200 upwards, causing the door panel 200 to flip. The top rod 310 can then be inserted into the positioning hole to support the flipped door panel 200. The collar 311 abutting against the square tube 300 further limits the insertion of the top rod 310 into the positioning hole. When not in use, the top rod 310 can be inserted into the square tube 300, and then both ends of the square tube 300 can be secured with rubber plugs 320. Both rubber plugs 320 abut against the push rod 310 inside the square tube 300, thereby limiting the push rod 310 and making it difficult for the push rod 310 to detach from the square tube 300. When the vehicle is moving, the two rubber plugs 320 abut against the push rod 310, making the push rod 310 less likely to shake, reducing the displacement of the push rod 310 inside the square tube 300 and reducing the impact force on the rubber plugs 320 that could cause the rubber plugs 320 to detach from the square tube 300. The inner wall of the positioning hole is threaded, and a screw can also be screwed into the positioning hole to abut against the push rod 310 to further fix the push rod 310.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0036] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
