[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0028] Example 1, referring to Figures 1-5 This is the first embodiment of the present utility model. This embodiment provides an isolation device for the construction of water conservancy and hydropower projects, including a main structure 1, including a first fence 11, a first extension fence 12 is provided in the inner cavity of the first fence 11, a second extension fence 13 is hinged to one side of the first extension fence 12, and a second fence 14 is provided on one side of the second extension fence 13.

[0029] The main structure 1 is the basic carrier for the device to achieve the isolation function. The first fence 11 and the second fence 14 serve as the basic support structure, providing a basic framework for the isolation range. The first extension bar 12 set in the inner cavity of the first fence 11 can extend and retract relative to the first fence 11. The design of the second extension bar 13 and the first extension bar 12 being hinged breaks the limitations of the traditional fixed structure, allowing both to rotate around the hinge point. The cooperation between the second extension bar 13 and the second fence 14 makes the main structure 1 a complete structure that is both extendable and foldable. This design allows the main structure 1 to change its overall length by extending and retracting to adapt to the isolation needs of different construction sites, and to reduce its volume by folding at the hinge point, solving the problem of large storage space occupation.

[0030] The connecting component 2 includes a locking block 21 fixedly connected to the surface of the first fence 11, and a locking groove 22 is provided on the surface of the second fence 14 and cooperates with the locking block 21. A fixing member 23 is provided in the inner cavity of the locking groove 22.

[0031] The locking block 21 on the surface of the first fence 11 and the locking groove 22 on the surface of the second fence 14 cooperate with each other to achieve the initial positioning of the first fence 11 and the second fence 14 after folding. The fixing member 23 in the inner cavity of the locking groove 22 can firmly fix the locking block 21 in the locking groove 22, preventing the device from being accidentally unfolded after folding and ensuring the stability of the storage state.

[0032] Example 2, refer to Figures 1-5 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0033] Specifically, the inner cavities of the first fence 11 and the second fence 14 are both provided with sliding grooves 15, and the top and bottom of the first extension fence 12 and the second extension fence 13 are both fixedly connected with sliders.

[0034] The sliding grooves 15 opened in the inner cavities of the first fence 11 and the second fence 14 form a sliding engagement with the sliders fixed at the top and bottom of the first extension bar 12 and the second extension bar 13. This firstly plays a precise limiting role, clearly defining the extension and retraction trajectory of the first extension bar 12 relative to the first fence 11 and the second extension bar 13 relative to the second fence 14, avoiding problems such as deviation and jamming during the extension and retraction process, and ensuring the smoothness of the extension and retraction process.

[0035] Specifically, the surface of the slider is fixedly connected to a pulley 16, which cooperates with the slide groove 15.

[0036] The design of pulley 16 transforms the sliding friction between the slider and the groove 15 into rolling friction, significantly reducing the friction between them. This improvement allows operators to more easily extend and retract the first extension bar 12 and the second extension bar 13 when adjusting the isolation length.

[0037] Specifically, the fastener 23 includes a fixing rod 231 disposed in the inner cavity of the slot 22, one side of the fixing rod 231 passing through the second fence 14 and extending to the outside of the second fence 14.

[0038] The fixing rod 231 can directly act on the card block 21 in the card slot 22, and fixation is achieved by inserting the corresponding structure of the card block 21; the design that extends through to the outside provides the operator with a convenient operating position, which makes it easy for the operator to control the displacement of the fixing rod 231 through external operation, so as to fix or unlock the card block 21.

[0039] Specifically, the surface of the card block 21 is provided with a fixing groove 232, which cooperates with the fixing rod 231.

[0040] The opening of the fixing groove 232 provides a dedicated locking point for the fixing rod 231. When the locking block 21 enters the locking groove 22, the fixing rod 231 can be accurately inserted into the fixing groove 232 to form a concave-convex fitting fixing structure. Compared with simple surface contact fixing, this fitting method greatly improves the stability of the fixing and effectively prevents the locking block 21 from shifting in the locking groove 22 after folding, thus avoiding accidental unfolding of the device.

[0041] Specifically, an arc-shaped spring piece 233 is fixedly connected to the surface of the second fence 14, and one side of the arc-shaped spring piece 233 is fixedly connected to the fixing rod 231.

[0042] When the operator presses the arc-shaped spring 233, the arc-shaped spring 233 undergoes elastic deformation, causing the fixing rod 231 to shift, making room for the locking block 21 to enter the locking slot 22; when the locking block 21 is fully inserted into the locking slot 22, the arc-shaped spring 233 is released, and under the action of elastic restoring force, it causes the fixing rod 231 to automatically reset and accurately insert into the fixing slot 232 to complete the fixation. This design simplifies the operation steps and reduces the difficulty of operation.

[0043] Specifically, reset grooves 234 are provided at the top and bottom of the inner cavity of the card slot 22, and springs 235 are fixedly connected to the inner cavity of the reset grooves 234.

[0044] When the locking block 21 enters the locking slot 22, it compresses the spring 235, converting mechanical energy into elastic potential energy for storage. When the device needs to be deployed, the locking block 21 is released from the fixing rod 231, and the spring 235 releases its elastic potential energy, generating a force that pushes the locking block 21, assisting the locking block 21 to detach from the locking slot 22. This design eliminates the need for operators to exert considerable effort to pull apart the first fence 11 and the second fence 14, reducing the difficulty of deployment and improving operational efficiency.

[0045] Specifically, a reset plate 236 is fixedly connected to one side of the spring 235 and cooperates with the locking block 21. The reset plate 236 is slidably connected to the reset groove 234.

[0046] When the locking block 21 enters the locking slot 22, the locking block 21 first contacts the reset plate 236. The reset plate 236 compresses the spring 235, avoiding the problem of uneven force or damage to the spring 235 caused by the locking block 21 directly contacting the spring 235. The sliding fit between the reset plate 236 and the reset slot 234 ensures that the reset plate 236 moves along a fixed trajectory during the compression and reset process, so that the elastic force of the spring 235 can act on the locking block 21 evenly and stably.

[0047] Specifically, threaded holes are provided at the bottom of both the first fence 11 and the second fence 14, and ground nails 17 are threaded into the inner cavity of the threaded holes.

[0048] The ground stake 17 effectively prevents the device from shifting or tipping over during construction due to factors such as wind, personnel collisions, or water flow impacts, ensuring the safety of the isolation area and adapting to the complex and ever-changing site environment of water conservancy and hydropower construction; while the threaded connection facilitates disassembly and assembly.

[0049] Specifically, foot pedals 18 are fixedly connected to the other side of both the first fence 11 and the second fence 14, and anti-slip mats 19 are fixedly connected to the top of the foot pedals 18.

[0050] The design of the foot pedal 18 and the anti-slip pad 19 provides convenient assistance for the installation of the ground stake 17 and improves the safety of operation.

[0051] Working principle: When the isolation length needs to be adjusted to fit the construction site, the telescopic design of the first extension bar 12 and the first fence 11, and the second extension bar 13 and the second fence 14, combined with the sliding limit of the top and bottom sliders of the first extension bar 12 and the second extension bar 13 in the inner cavity of the first fence 11 and the second fence 14, and the rolling cooperation of the pulley 16 on the surface of the slider and the sliding groove 15, allows the operator to push the first extension bar 12 relative to the first fence 11 and the second extension bar 13 relative to the second fence 14 to extend and retract. The pulley 16 reduces the sliding friction, making the adjustment smoother, while the sliding groove 15 and the slider ensure accurate extension and retraction trajectory and avoid deviation, thereby realizing flexible adjustment of the isolation length and solving the problem of fixed length of existing devices.

[0052] When space-saving storage is required, first retract the first extension bar 12 into the inner cavity of the first fence 11, and retract the second extension bar 13 into the inner cavity of the second fence 14. Then rotate around the hinge point of the first extension bar 12 and the second extension bar 13 to bring the first fence 11 and the second fence 14 closer together for folding. During the folding process, the locking block 21 on the surface of the first fence 11 gradually enters the locking groove 22 on the surface of the second fence 14. At this time, the operator presses the arc-shaped spring piece 233 connected to the fixing rod 231, causing it to deform and drive the fixing rod 231 to move, making room for the locking block 21 to fully enter the locking groove 22. When the locking block 21 enters, it will squeeze the reset plate 236, causing it to slide in the reset groove 234 and compress the spring 235. After the locking block 21 is fully in, release the arc-shaped spring piece 233, and its reset will drive the fixing rod 231 to insert into the fixing groove 232 on the surface of the locking block 21, completing the folding and fixing, realizing the reduction of device size and solving the problem of large storage space.

[0053] When the device needs to be deployed, press the arc-shaped spring piece 233 to disengage the fixing rod 231 from the fixing groove 232. The compressed spring 235 releases its elastic potential energy, pushing the reset plate 236 to push the locking block 21 out of the locking groove 22. Then, the first fence 11 and the second fence 14 are deployed, and the extension fence is extended to adjust the length.

[0054] When the device is fixed, the ground nail 17 is inserted into the ground. The operator can step on the foot pedal 18 on the other side of the fence to assist in exerting force. The anti-slip pad 19 on the foot pedal 18 prevents slipping when stepping, ensuring that the ground nail 17 is firmly fixed and improving the stability of the device.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
