Abstract
Description
Technical Field
[0001] This utility model relates to the field of hydropower station signage management technology, and in particular to an automatically adjustable storage box for storing hydropower station safety signs. Background Technology
[0002] Hydropower generation utilizes the potential energy of water flowing from high-altitude areas such as rivers and lakes to lower-altitude areas, converting the potential energy into the kinetic energy of water turbines. The turbines then drive generators to produce electricity. During the operation of hydropower equipment, the switch positions of various devices differ, and maintenance of different devices is also frequently required. When hydropower station equipment is under maintenance or in operation, or when certain locations on site pose safety risks and should be avoided, hydropower station staff will hang safety signs on the relevant equipment or locations to remind those not involved.
[0003] Therefore, safety signs are frequently used in the equipment management of hydropower stations. Placing safety signs in important locations can serve as a warning and prevent workers from accidentally touching equipment and causing malfunctions. In a single hydropower station project, there are hundreds of safety signs used, which is a huge number. They come in many different types, and the sizes of different types of safety signs vary, making the management of safety signs quite difficult.
[0004] Currently, safety signs are managed by categorizing and stacking them. In open areas on site, safety signs are categorized and stacked together. When needed, the corresponding safety sign is found and hung. This management method is time-consuming to find safety signs, and the stacking method leads to a messy site environment and makes it easy for safety signs to be lost. When a large number of safety signs are needed, staff have to search for them one by one, resulting in low work efficiency. Utility Model Content
[0005] To overcome the above problems, the purpose of this utility model is to provide an automatically adjustable storage box for storing safety signs in hydropower stations. The box includes a body, a lid, an automatic sign-pushing mechanism, a latch, a first handle, and a second handle. The storage box uses the sign-pushing mechanism to advance the sign after it is removed, ensuring that the next sign to be retrieved is at the exit position, avoiding the time wasted searching. Simultaneously, a hanging rope slot is provided on the lid, allowing all sign hanging ropes to pass through this slot and exit outside the box. A sign retrieval slot facilitates the retrieval of signs; the corresponding sign can be retrieved directly from the slot using the external hanging rope, improving work efficiency. Finally, the storage box employs a baffle adjustment mechanism to adjust the size of the box, ensuring that the width of the cross-section of the internal storage space is the same as the width of the sign to be placed. This makes it suitable for storing safety signs of different sizes and has a wide range of applications.

[0041] like Figures 1-9 As shown, it illustrates a specific embodiment of this utility model:
[0042] Example 1
[0043] The present invention discloses an automatically adjustable storage box for storing safety signs in hydropower stations, comprising a box body 1, a box cover 2, an automatic sign pushing mechanism 3, buckles 4, a first handle, and a second handle. The box body 1 adopts a cuboid structure. The box cover 2 is rotatably connected to one side of the upper surface of the box body 1. The automatic sign pushing mechanism 3 is installed inside the box body 1. There are two buckles 4, which are respectively installed on the left and right sides of the front of the box body 1 and the box cover 2. Part of the buckle 4 is installed on the box body 1, and the other part is installed on the box cover 2.
[0044] In this embodiment, as Figure 2 As shown, the storage box uses a sign-pushing mechanism 3 to push the signs placed in the box 1 forward after one sign is taken out, ensuring that the next sign to be retrieved is located at the exit position, avoiding the time wasted searching again. The buckles 4 on the box 1 and the lid 2 open when the safety signs are placed, making it easy to place the safety signs. After placement, they are fastened again. The storage box facilitates the storage and organization of safety signs and improves work efficiency.
[0045] The lid 2 has a hanging rope slot 21 and a sign retrieval slot 22 on its upper part. The hanging rope slot 21 is located in the middle of the lid 2, and the sign retrieval slot 22 is located to the right of the hanging rope slot 21.
[0046] In this embodiment, as Figure 1As shown, a hanging rope through slot 21 is provided on the box cover 2, so that the hanging ropes of all the signs are located outside the box body 1 through the hanging rope through slot 21. A sign retrieval slot 22 is provided to facilitate the retrieval of the signs. The corresponding signs can be directly taken out from the sign retrieval slot 22 through the external hanging rope, thereby improving work efficiency.
[0047] Among the existing safety signs in hydropower stations, there are both hook-on safety signs and magnetic safety signs. Magnetic safety signs are mainly used on metal equipment and are directly attached to the equipment. Hook-on safety signs are used in other locations where they cannot be attached. In actual storage, due to the differences between different types of signs, hook-on safety signs are provided with hook-on slots 21 to facilitate the orderly storage of hook-on safety signs. When storing them in combination, labels can be designed on the exposed parts of the signs to facilitate finding them and improve efficiency.
[0048] The automatic signage propulsion mechanism 3 includes a first guide rail 31, a first slider 32, a second guide rail 33, a second slider 34, a first push plate 35, and a first telescopic spring 36. The first guide rail 31 and the second guide rail 33 have the same structure and are fixedly installed on the front and rear sides of the bottom of the housing 1, respectively. The first slider 32 is slidably connected to the left side inside the first guide rail 31, and the second slider 34 is slidably connected to the left side inside the second guide rail 33. The first push plate 35 has the same cross-sectional size as the inside of the housing 1. The bottom of the first push plate 35 is fixedly connected to the upper surface of the first slider 32 and the second slider 34. One end of the first telescopic spring 36 is fixedly connected to the left side inside the housing 1, and the other end is fixedly connected to the side of the first push plate 35.
[0049] In this embodiment, as Figure 2 As shown, when storing the sign, the first push plate 35 is pushed to the leftmost position, at which point the first telescopic spring 36 is compressed, and the safety sign is placed in this space for storage. When the safety sign is needed, it is retrieved through the sign retrieval slot 22 on the box cover 2. After the sign is taken out from the sign retrieval slot 22, the compressed first telescopic spring 36 pushes the first push plate 35 forward under the action of elastic force. The first slider 32 and the second slider 34, which are fixedly connected to the lower surface of the first push plate 35, slide on the first guide rail 31 and the second guide rail 33 respectively, so that the remaining sign is pushed out to the position of the sign retrieval slot 22, ensuring that the safety sign is always below the sign retrieval slot 22 for easy retrieval.
[0050] Specifically, the width and height of the cross-section of the box 1 are both greater than the maximum width and maximum height of the signage used by the hydropower station.
[0051] In this embodiment, the cross-sectional dimensions of the box 1 are designed to accommodate the storage of all safety signs in the hydropower station.
[0052] Example 2
[0053] There are various types of safety signs used in actual hydropower station operations, including:
[0054] 25cm*25cm, with signs indicating "Working here", "Maintenance area", "Please register before entering or leaving" etc.
[0055] 24cm*30cm, with signs on it indicating "No throwing objects", "Caution: Trip up", "Do not cross over", "No entry without permission" and other similar messages;
[0056] 6cm*8cm, marked with "Do not operate, people are working" and "Do not close the switch, people are working".
[0057] To enable the storage box to use safety signs of different sizes, this second embodiment is proposed.
[0058] Specifically, it also includes a baffle adjustment mechanism 5, which is installed between the first guide rail 31 and the second guide rail 33.
[0059] In this embodiment, the baffle adjustment mechanism 5 can adjust the size of the cross-section inside the storage space of the box 1 so that the cross-section of the placement space inside the box 1 is the same as the area of the sign to be placed. It is suitable for storing safety signs of different sizes and has a wide range of applications.
[0060] Specifically, the baffle adjustment mechanism 5 includes a first baffle fixing plate 51, a second baffle fixing plate 52, a first baffle 53, and a second baffle 54. The first baffle fixing plate 51 is fixedly installed at the left end of the first guide rail 31 and the second guide rail 33, and the second baffle fixing plate 52 is fixedly installed at the right end of the first guide rail 31 and the second guide rail 33. The first baffle fixing plate 51 and the second baffle fixing plate 52 have the same structure, and their upper surfaces are evenly provided with first mounting holes 511. The first baffle 53 and the second baffle 54 have the same structure, and their bottom surfaces are provided with first mounting posts 531 at both ends. The dimensions of the first mounting posts 531 are adapted to the dimensions of the first mounting holes 511.
[0061] In this embodiment, as Figure 4 , Figure 5As shown, the first baffle fixing plate 51 and the second baffle fixing plate 52 are used to fix the first baffle 53 and the second baffle 54. By adjusting the position of the first mounting post 531 below the first baffle 53 and the second baffle 54, the distance between the first baffle 53 and the second baffle 54 is adjusted, so that the cross-sectional width of the storage space inside the box 1 is the same as the width of the safety sign to be stored, so that the safety signs inside the storage box are stored in an orderly manner. It is suitable for storing safety signs of different sizes and specifications and has a wide range of applications.
[0062] The first push plate 35 has a uniformly provided mounting groove 351 at its lower end. The width of the mounting groove 351 is the same as the thickness of the first baffle 53 and the second baffle 54. The bottom surfaces of the first push plate 35 are provided with second mounting posts 352. The upper surfaces of the first slider 32 and the second slider 34 are provided with second mounting holes 321. The dimensions of the second mounting posts 352 and the second mounting holes 321 are adapted to each other.
[0063] Specifically, the height of the mounting groove 351 of the first push plate 35 is the same as the height of the first baffle 53 and the second baffle 54.
[0064] In this embodiment, as Figure 3 , Figure 6 As shown, mounting grooves 351 are evenly provided below the first push plate 35, so that after the first baffle 53 and the second baffle 54 are adjusted, the first push plate 35 can also slide towards the signboard retrieval groove 22 under the action of the first telescopic spring 36. The design of the second mounting post 352 and the second mounting hole 321 allows the first push plate 35 to be disassembled at any time. After the positions of the first baffle 53 and the second baffle 54 are adjusted appropriately, the first push plate 35 is then connected to the first slider 32 and the second slider 34. The whole operation is simple and convenient.
[0065] Example 3
[0066] Specifically, the baffle adjustment mechanism 5 further includes a second telescopic spring 55, a second push plate 56, a third slider 57, and a fourth slider 58. One end of the second telescopic spring 55 is fixedly installed inside the right side of the housing 1, and the other end is fixedly connected to the side of the second push plate 56. The second push plate 56 has the same structure as the first push plate 35. The third slider 57 is slidably connected to the right side of the first guide rail 31, and the fourth slider 58 is slidably connected to the right side of the second guide rail 33. The second push plate 56 is connected to the upper surfaces of the third slider 57 and the fourth slider 58.
[0067] Specifically, the hanging rope slot 21 on the box cover 2 can also be set on the left and right sides in the middle, and the sign retrieval slot 22 is located in the middle of the hanging rope slot 21.
[0068] In this embodiment, as Figure 7 , Figure 8 , Figure 9 As shown, a third slider 57 and a fourth slider 58 are provided, allowing the second push plate 56, mounted on the third slider 57 and the fourth slider 58, to slide on the right side of the box. A second telescopic spring 55 is also provided, which provides elastic force to the second push plate 56. In addition to bidirectional telescopic movement, when storing safety signs in combination, a sign retrieval slot 22 is provided in the middle of the box cover 2. Retrieval is done from the middle position, avoiding the situation where the signs needed for single-sided storage are located on the innermost side, requiring the removal of all signs. Thus, when storing in combination, the storage capacity on both sides is the same, and retrieving from the middle position improves efficiency.
[0069] Example 4
[0070] Specifically, the first baffle 53, the second baffle 54, and the first push plate 35 are all made of hard plastic.
[0071] Specifically, the second push plate 56 is made of hard plastic.
[0072] In this embodiment, the materials inside the box 1 are all made of rigid plastic, which can ensure that the storage space is fixed when the safety signs are stored, and ensure orderly management of the safety signs.
