Description

Technical Field

[0001] This utility model relates to the field of power design technology, specifically to a line protection device for power design. Background Technology

[0002] In the planning process of power design, temporary line laying is inevitable. Cables of different specifications should be placed in layers according to voltage level and wire diameter to avoid confusion and damage, thereby achieving the purpose of protecting the cables.

[0003] Multiple wall-mounted brackets are installed using expansion screws. While this achieves layered support, the installation process is rather cumbersome, requiring drilling and screwing. Furthermore, installation marks are left after disassembly, necessitating secondary processing. While existing technologies offer convenient installation and removal of integrated layered support frames, their large overall structure makes them inconvenient to move and store. Furthermore, their high center of gravity makes them unstable and prone to tipping over when cables are being pulled or adjusted.

[0004] Therefore, in order to solve the above problems, a line protection device for power design is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a line protection device for power design that is stable and reliable when supporting cables in layers, and is also more convenient to move, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A line protection device for power design includes a storage box and a tray. The tray consists of 2 to 6 trays evenly distributed along the vertical direction. The front sides of the trays are connected and assembled via a telescopic barrier structure. The storage box is fixedly installed on the lower side of the bottom tray, and a locking structure for limiting the telescopic barrier structure is installed on the front side of the top tray. A pair of brake casters are installed on the left end of the storage box and the left end of the uppermost tray. A manual valve is connected to the left end of the upper surface of the storage box, and a feed inlet is connected to the right end of the upper surface of the storage box. The feed inlet is fitted with a cap that is threaded onto it.

[0007] Specifically, the telescopic barrier structure includes elongated holes, pins, and connecting rods. The left end of the front side of the support plate is horizontally provided with elongated holes. The connecting rods are hinged to form X-shaped groups by a central pin. The upper and lower adjacent X-shaped groups are hinged to each other by pins at the ends of the connecting rods. The pin on the left side is slidably installed in the elongated hole, and the pin on the right side is rotatably assembled with the support plate.

[0008] Furthermore, at least one pair of left-right aligned pins is fitted with a tension spring.

[0009] Specifically, the locking structure includes a lever, a rotating seat, and an L-shaped locking block. A pair of rotating seats are fixedly installed on the front side of the uppermost tray. An L-shaped locking block is rotatably installed between each pair of rotating seats via a torsion spring. The L-shaped locking block is located directly above the elongated hole. A lever is fixedly installed at the front end of the L-shaped locking block, and the lower end of the L-shaped locking block extends into the tray.

[0010] Furthermore, when the trays are stacked and stored, the uppermost and leftmost pin engages with the left end of the L-shaped block; when the trays are unfolded for use, the uppermost and leftmost pin engages with the right end of the L-shaped block.

[0011] Specifically, the cross-section of the tray is U-shaped.

[0012] Specifically, a handle is fixedly installed on the right end of the storage box.

[0013] Compared with the prior art, the beneficial effects of this utility model are: Multiple trays, through the cooperation of telescopic railing and locking structures, achieve two working states: stacked storage and unfolded use, making setup and dismantling very convenient.

[0014] By filling the storage tank with water to increase the weight at the bottom, the device is placed more stably, avoiding the problem of the support frame easily tipping over when the cables are pulled or adjusted. At the same time, after draining the water, the overall weight is reduced, and with the cooperation of brake casters and handles, it is easier to move the whole device. Attached Figure Description

Detailed Implementation

[0017] 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.

[0018] Please see Figure 1 This utility model provides a line protection device for power design.

[0019] Explanation regarding the ability of multiple trays 6 to achieve stacked screw storage and unfolding use: It mainly includes a storage box 1 and trays 6. The storage box 1 is a rectangular box, which is filled with materials to increase the weight at the bottom and make it more stable. There are 2 to 6 trays evenly distributed along the vertical direction. The cross-section of the trays 6 is U-shaped. The trays 6 are all set horizontally for layered storage of cables. The U-shaped cross-section can also prevent the cables from slipping, thus meeting the needs of layered cable storage.

[0020] The front side of the tray 6 is connected and assembled through the telescopic railing structure 4. The storage box 1 is fixedly installed on the lower side of the bottom tray 6, and the locking structure 5 for limiting the telescopic railing structure 4 is installed on the front side of the top tray 6. The telescopic railing structure 4 is used to synchronously adjust the distance between all the trays 6, and can realize two working states: stacked storage and unfolded use. It can be quickly locked through the locking structure 5.

[0021] Regarding its overall portability and ease of use: A pair of brake casters 9 are installed on the left end of the storage box 1 and the left end of the uppermost tray 6. These brake casters 9 are existing components with brakes, which can lock the wheels when needed by the operator to prevent movement, and allow for flexible omnidirectional movement only after unlocking. The trays 6 are stacked and screwed together counterclockwise (towards...). Figure 1 (Using the direction as a reference) After the whole structure is erected, the two pairs of brake casters 9 on the left side form a stable support at the four corners, which can be used to support the whole structure and facilitate transfer and positioning.

[0022] A manual valve 2 is connected to the left end of the upper surface of the storage box 1, and a feed inlet is connected to the right end of the upper surface of the storage box 1. The feed inlet is connected to a cap 7 with an external thread. When it is necessary to fill the storage box 1 with material (preferably water), open the cap 7 and the manual valve 2, and water is delivered through the feed inlet until the storage box 1 is full. During the process, the air squeezed out of the storage box 1 is discharged from the manual valve 2, which can quickly balance the internal and external air pressure and facilitate the smooth entry of water. After completion, tighten the cap 7 and close the manual valve 2 for sealed storage.

[0023] After the entire unit is used up and the tray 6 is stored, move the entire unit to the sewer. At this time, the entire unit is in an upright position, and the manual valve 2 is located at the bottom. Opening the manual valve 2 will drain the water in the storage tank 1.

[0024] In addition, to facilitate the erection or placement of the storage box 1, a handle 8 is fixedly installed on the right end of the storage box 1 to facilitate the operator to apply force.

[0025] Please see Figure 2 The specific structure of telescopic fence structure 4: The telescopic barrier structure 4 includes an elongated hole 41, a pin 42, and a connecting rod 43. The left end of the front side of the support plate 6 is provided with an elongated hole 41. The connecting rod 43 is hinged to form an X-shaped group by a central pin. The upper and lower adjacent X-shaped groups are hinged to each other by the pin 42 at the end of the connecting rod 43. The pin 42 on the left side is slidably installed in the elongated hole 41, and the pin 42 on the right side is rotatably assembled with the support plate 6.

[0026] The X-shaped linkage can change the included angle between the connecting rods 43 (the included angle refers to the two opposite corners) with the center pin as the center, thereby realizing the cross swing action. After being driven by the pin 42, the X-shaped linkage can achieve the same swing amplitude and the same shape of all X-shaped linkages. With the right pin 42 as the support point, the left pin 42 slides along the elongated hole 41. When the included angle between the connecting rods 43 increases, the left pin 42 slides to the left along the elongated hole 41, thereby reducing the distance between adjacent support plates 6. When the included angle between the connecting rods 43 decreases, the left pin 42 slides to the right along the elongated hole 41, thereby increasing the distance between adjacent support plates 6.

[0027] In addition, to facilitate the smooth unfolding and use of the trays 6, i.e., to increase the distance between them, at least one pair of left-right aligned pins 42 are equipped with tension springs 3. The number of tension springs 3 depends on the number and weight of the trays 6. The more trays 6 there are and the heavier they are, the greater the force required for the telescopic barrier structure 4 to unfold all the trays 6. At this time, it is necessary to configure an appropriate number of tension springs 3 to ensure smooth and fast unfolding.

[0028] The tension spring 3 is installed by fixing hooks to the front ends of the pair of pins 42 and hanging the tension spring 3 between the hooks.

[0029] Please see Figure 3 The specific structure of locking structure 5: The locking structure 5 includes a lever 51, a rotating seat 52, and an L-shaped locking block 53. A pair of rotating seats 52 are fixedly installed on the front side of the uppermost support plate 6. An L-shaped locking block 53 is rotatably installed between each pair of rotating seats 52 via a torsion spring. The L-shaped locking block 53 is located directly above the elongated hole 41. The lever 51 is fixedly installed at the front end of the L-shaped locking block 53, and the lower end of the L-shaped locking block 53 extends into the support plate 6.

[0030] The rotating seat 52 is rotatably mounted with the L-shaped locking block 53 through a central shaft. A torsion spring is sleeved on the central shaft. One end of the torsion spring is fixedly assembled with the rotating seat 52, and the other end of the torsion spring is fixedly assembled with the L-shaped locking block 53, so that the L-shaped locking block 53 has a force to swing and reset towards the inside of the support plate 6.

[0031] In use, by moving the lever 51 downwards, it can rotate counterclockwise (with the rotating base 52 as the base) Figure 3 (Referring to the direction) Rotate the L-shaped locking block 53 so that the lower end of the L-shaped locking block 53 is away from the elongated hole 41, making room for the uppermost and leftmost pin 42 to slide; after releasing the lever 51, the L-shaped locking block 53 can swing back to its original position under the action of the torsion spring and press against the elongated hole 41 again. At this time, the uppermost and leftmost pin 42 has no room to slide.

[0032] That is, when the tray 6 is stacked and stored, the uppermost and leftmost pin 42 is engaged with the left end of the L-shaped block 53. When the tray 6 is unfolded for use, the uppermost and leftmost pin 42 is engaged with the right end of the L-shaped block 53. The sliding of the uppermost and leftmost pin 42 is restricted by the blocking of the L-shaped block 53, thereby limiting the shape of the telescopic railing structure 4 and realizing the switching function of storage and unfolding.

[0033] The working principle of this embodiment: When the device is in its stored state and needs to be unfolded for use: First, lay the whole thing down and put water into the storage box 1 through the feed inlet. After it is full, seal it. Then, push down the lever 51 in the operation locking structure 5. Rotate the lower end of the L-shaped card block 53 counterclockwise based on the rotating seat 52, so that the lower end of the L-shaped card block 53 is away from the elongated hole 41, making room for the pin 42 to slide.

[0034] Under the combined action of the telescopic barrier structure 4 and the tension spring 3, the telescopic barrier structure 4 can lift each tray 6 until the distance between the trays 6 reaches its maximum. At this time, the uppermost and leftmost pin 42 slides along the elongated hole 41 to the right end. After releasing the lever 51, the L-shaped locking block 53 is reset under the action of the torsion spring and re-locks the pin 42 here, so that the distance between the trays 6 will not change again. Afterwards, the trays 6 can be placed in layers as needed during the cable laying process.

[0035] When storage is needed: To unlock, press down on the topmost support plate 6 until they are stacked on top of each other. During this process, the telescopic bar structure 4 adapts and stretches the tension spring 3 until the topmost and leftmost pin 42 is located at the left end of the L-shaped block 53. Then release the lever 51 to relock.

[0036] The device can be easily moved and transferred by using the handle 8 and four brake casters 9. The manual valve 2 can also be opened when it is in the sewer. After drainage, the device is lighter and easier to carry.

[0037] 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, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0038] 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.
