Description

Technical Field

[0001] This application relates to the field of water conservancy engineering technology, specifically to a slope protection device for water conservancy construction. Background Technology

[0002] In hydraulic engineering construction, ramps are crucial passageways for personnel, equipment, and material transport. They also serve to prevent uncontrolled water flow and maintain the dryness of the construction area. Because ramp surfaces easily become slippery due to accumulated water and sediment, people walking or equipment moving are prone to slipping and falling, potentially causing injuries, equipment damage, and disruptions to construction progress. Therefore, the core objective of ramp protection in hydraulic engineering construction is to enhance the anti-slip performance of the ramp surface through protective structures, protecting the safety of construction personnel and equipment while maintaining the ramp's water-blocking function to ensure smooth construction operations. The prior art discloses a slope protection device for hydraulic construction, including anti-slip plates, guardrails, and fixing components. The anti-slip plates are rectangular metal plates with evenly distributed raised anti-slip textures on their surface. The anti-slip plates are spliced ​​and laid along the length of the slope. The guardrails consist of vertical bars and horizontal bars. The vertical bars are set vertically on both sides of the slope, and the horizontal bars are connected horizontally to adjacent vertical bars. The fixing components are expansion bolts, which penetrate the anti-slip plates and the vertical bars of the guardrails to fix the anti-slip plates and guardrails to the slope base. Rubber sealing strips are provided at the joints between the anti-slip plates to prevent water seepage. Existing protective devices can only provide anti-slip and basic protection. When the water level rises during the rainy season, they cannot promptly warn personnel to avoid the risks posed by the rising water level, which can easily lead to equipment being flooded and causing economic losses. Summary of the Invention Therefore, this application provides a slope protection device for hydraulic construction to solve the problem of the inability to provide early warning of rising water levels in the existing technology.

[0003] To achieve the above objectives, this application provides the following technical solution: In a first aspect, a slope protection device for hydraulic construction includes a protective net and a connecting plate. The connecting plate is disposed on opposite sides of the protective net, which is laid along the slope. The connecting plate is used to install the protective net on the slope. The device is characterized by further including a connecting rope, a float, a guide rod, an indicator light, and a trigger switch. One end of the connecting rope is connected to the connecting plate on the lower elevation side, and the other end extends freely along the slope towards the lower elevation side. The float is connected to the freely extending end of the connecting rope, and a limiting ring is provided at the end of the float away from the connecting rope. The guide rod is disposed on the slope along the direction of gravity, and the limiting ring is sleeved on the guide rod. The indicator light is disposed on the float and is a fully sealed waterproof light. The trigger switch is disposed inside the float and is electrically connected to the indicator light.

[0004] Optionally, a receiving cavity is formed within the float, and a trigger switch is disposed within the receiving cavity. The trigger switch includes an arc-shaped track, a metal roller, a trigger seat, and a battery pack. The arc-shaped track is disposed within the receiving cavity near the limiting ring, and includes a trigger end and a disconnect end. The trigger end is located at the end of the receiving cavity opposite to the indicator light, and the disconnect end is located at the end of the receiving cavity away from the connecting rope. The metal roller has a degree of freedom of movement along the arc-shaped track. The trigger seat is disposed on one side of the trigger end, and the metal roller can roll along the arc-shaped track into the trigger seat. The battery pack is disposed on the side of the trigger seat opposite to the indicator light. The trigger seat is electrically connected to both the indicator light and the battery pack.

[0005] Optionally, a signal transmitter is also provided in the accommodating cavity, and the signal transmitter is electrically connected to the trigger seat and the indicator light.

[0006] Optionally, the arc-shaped track includes a track plate with an arc of π / 4 and guide grooves on both sides. The two ends of the metal roller extend into the guide grooves. The guide groove is closed at one end of the disconnection end and open at one end of the trigger end.

[0007] Optionally, the battery pack includes a battery holder and a battery block; wherein the battery holder includes a mounting groove and a connection port, and the battery holder is disposed in the accommodating cavity; the battery block is installed in the mounting groove; wherein the connection port is electrically connected to the trigger seat.

[0008] Optionally, the float comprises two hemispherical shells, which are bonded together by a sealant.

[0009] Optionally, the limiting ring and the float are bonded together with sealant.

[0010] Optionally, a waterproof coating is filled between the indicator light and the hemispherical outer shell.

[0011] Compared with the prior art, this application has at least the following beneficial effects: 1. By combining the protective net and the connecting plate, the stability of the device on the slope is ensured, and the mud and sand are blocked to reduce the risk of slipping on the slope. This continues and optimizes the core function of traditional protection: anti-slip and water-blocking. At the same time, an innovative early warning structure consisting of connecting ropes, floats, guide rods, indicator lights, and trigger switches is added. The floats move vertically along the guide rods as the water level changes, and the trigger switches can precisely control the on / off state of the fully sealed waterproof indicator lights. This solves the key defect of existing devices that can only prevent slipping and water blocking but cannot cope with rising water levels during the rainy season. It realizes on-site visual early warning of water level risks and effectively avoids equipment flooding and economic losses. 2. The float adopts a double hemispherical shell sealing adhesive bonding structure, combined with the sealing adhesive connection between the limit ring and the float, and the waterproof coating between the indicator light and the shell, forming a full-dimensional waterproof protection to prevent water or moisture from seeping into the interior and damaging electrical components; the arc-shaped track built into the trigger switch adapts to the linkage of gravity and buoyancy, the metal roller achieves circuit connection without power drive, and the independent battery pack ensures accurate warning triggering and adapts to the problem of inconvenient power supply in construction scenarios. The addition of a signal transmitter upgrades the warning from "on-site reminder" to "remote transmission", expanding the warning coverage and avoiding warning omissions due to personnel not being present; 3. The detachable hemispherical float design facilitates the installation and maintenance of internal trigger switches, battery packs, and other components. The standardized battery holder mounting slots and connection structures simplify the battery replacement process, eliminating the need for complex wiring operations. The optimized structure, including the guide rod limiting float displacement and the arc-shaped track guide groove preventing metal roller jamming, ensures stable operation of the device in humid and high-flow-impact hydraulic construction environments, extending its overall service life. Ultimately, through functional integration and structural optimization, it provides more comprehensive and reliable safety assurance for hydraulic construction ramps, helping to maintain stable construction progress.

[0015] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0016] In the description of this application: unless otherwise stated, "a plurality of" means two or more. The terms "first," "second," "third," etc., in this application are intended to distinguish the objects referred to and do not have any special meaning in terms of technical connotation (e.g., they should not be construed as an emphasis on importance or order). Expressions such as "including," "comprising," and "having" also mean "not limited to" (certain units, components, materials, steps, etc.).

[0017] The terms used in this application, such as "upper," "lower," "left," "right," and "middle," are generally used to facilitate intuitive understanding by referring to the accompanying drawings, and are not absolute limitations on the positional relationships in the actual product. Changes in these relative positional relationships, without departing from the technical concept disclosed in this application, should also be considered within the scope of this application.

[0018] The following is combined Figures 1 to 6 The embodiments shown illustrate the technical solution of this utility model: This utility model embodiment provides a slope protection device for hydraulic construction, such as... Figures 1-3 As shown, the device includes a protective net 1 and a connecting plate 2. The connecting plate 2 is located on opposite sides of the protective net 1. The protective net 1 is laid along the slope, and the connecting plate 2 is used to install the protective net 1 on the slope. The device is characterized by further including a connecting rope 7, a float 3, a guide rod 4, an indicator light 5, and a trigger switch 6. One end of the connecting rope 7 is connected to the connecting plate 2 on the lower elevation side, and the other end extends freely along the slope towards the lower elevation side. The float 3 is connected to the freely extending end of the connecting rope 7, and a limiting ring 302 is provided at the end of the float 3 away from the connecting rope 7. The guide rod 4 is set on the slope along the direction of gravity, and the limiting ring 302 is sleeved on the guide rod 4. The indicator light 5 is located on the float 3 and is a fully sealed waterproof light. The trigger switch 6 is located inside the float 3 and is electrically connected to the indicator light 5.

[0019] Specifically, the protective net 1 and the connecting plate 2 form a basic fixing structure to ensure the stability of the device on the slope. At the same time, the protective net 1 can help block some mud and sand, reducing the risk of slipping on the slope. The connecting rope 7 connects the float 3 to the protective net 1, ensuring the synchronous displacement of the float 3 as the water level changes. The guide rod 4 is set along the direction of gravity and restricts the float 3 to move only in the vertical direction through the limiting ring 302, preventing the float 3 from deviating from the warning monitoring position due to water flow impact. The fully sealed waterproof light design can prevent rainwater or water accumulation from entering the indicator light 5 and causing short circuit damage, ensuring normal operation in humid environments. The electrical connection structure between the trigger switch 6 and the indicator light 5 can trigger the indicator light 5 to light up when the float 3 rises to a specific position with the water level, realizing on-site visual warning of rising water level, solving the core problem of no warning in existing technology, and reducing the risk of equipment flooding and economic losses.

[0020] It should be noted that in practical applications, multiple sets of protective nets 1 are laid to fully cover the slope, and floats 3 are connected to the water at different heights to provide early warning of safe water levels.

[0021] In an exemplary embodiment, see Figure 3 A accommodating cavity is formed inside the float 3, and a trigger switch 6 is located inside the accommodating cavity. The trigger switch 6 includes an arc-shaped track 601, a metal roller 602, a trigger seat 605, and a battery pack 603. The arc-shaped track 601 is located in the accommodating cavity near the limiting ring 302 and includes a trigger end and a disconnect end. The trigger end is located at the end of the accommodating cavity away from the indicator light 5, and the disconnect end is located at the end of the accommodating cavity away from the connecting rope 7. The metal roller 602 has a degree of freedom of movement along the arc-shaped track 601. The trigger seat 605 is located on the trigger end side, and the metal roller 602 can roll into the trigger seat 605 along the arc-shaped track 601. The battery pack 603 is located on the side of the trigger seat 605 away from the indicator light 5. The trigger seat 605 is electrically connected to the indicator light 5 and the battery pack 603 respectively.

[0022] Specifically, the accommodating cavity provides a closed protective space for all components of the trigger switch 6, preventing external water and sediment from entering and extending the service life of the trigger switch 6; the trajectory design of the arc-shaped track 601 adapts to the attitude adjustment of the float 3 as the water level changes, and the position division between the trigger end and the disconnect end clearly defines the water level threshold for "warning trigger" and "non-warning", ensuring the accuracy of the warning; the rolling design of the metal roller 602 uses the linkage of gravity and buoyancy to realize the circuit switching, without the need for an additional power source, improving the energy efficiency and reliability of the device; the trigger seat 605, as an electrical connection transfer component, can ensure stable conductivity after the metal roller 602 enters, avoiding poor contact that could lead to warning failure; the battery pack 603 provides independent power supply for the indicator light 5, without the need for an external power source, adapting to environments where power supply is inconvenient in water conservancy construction scenarios, further improving the applicability of the device.

[0023] In an exemplary embodiment, see Figure 3 and Figure 4 The cavity is also equipped with a signal transmitter 604, which is electrically connected to the trigger seat 605 and the indicator light 5.

[0024] Specifically, the addition of signal transmitter 604 upgrades the water level warning signal from "on-site visualization" to "remote transmission." In addition to the on-site indicator light 5, it can also send warning signals to remote devices such as the construction monitoring center and management personnel terminals, solving the problem that existing on-site warnings are prone to being missed due to personnel absence. Its synchronous electrical connection with trigger seat 605 and indicator light 5 ensures the consistency between the transmission of the warning signal and the lighting of indicator light 5, avoiding signal delay or misalignment, expanding the warning coverage, further improving the timeliness and effectiveness of water level warnings, and reducing the potential risk of equipment flooding.

[0025] In an exemplary embodiment, see Figure 5 The arc track 601 includes a track plate 6011 with an arc of π / 4 and guide grooves on both sides. The two ends of the metal roller 602 extend into the guide grooves. The guide groove is closed at the disconnection end and open at the trigger end.

[0026] Specifically, the π / 4 arc of the track plate 6011 is mechanically adapted to ensure that the metal roller 602 rolls smoothly along the track under gravity when the float 3 rises with the water level; the guide groove can limit the lateral displacement of the metal roller 602, prevent the metal roller 602 from deviating from the track during rolling, and ensure that it always moves along the preset trajectory; the closed design of the disconnect end prevents the metal roller 602 from leaving the track, ensuring the stable stay of the metal roller 602 in the non-warning state; the open design of the trigger end eliminates the structural obstruction of the metal roller 602 entering the trigger seat 605, ensuring the smoothness of circuit switching and improving the reliability of the trigger switch 6.

[0027] In an exemplary embodiment, referring to 6, the battery pack 603 includes a battery holder 6031 and a battery block 6032; wherein, the battery holder 6031 includes a mounting groove 60311 and a connection port 60312, and the battery holder 6031 is disposed in the accommodating cavity; the battery block 6032 is installed in the mounting groove 60311; wherein, the connection port 60312 is electrically connected to the trigger seat 605.

[0028] Specifically, the mounting slot 60311 of the battery holder 6031 can mechanically fix the battery block 6032, preventing poor contact caused by the shaking of the battery block 6032 during the movement of the float 3, and ensuring the stability of power supply; the independent battery block 6032 structure facilitates later replacement and maintenance, avoids the scrapping of the entire trigger switch 6 due to battery failure, reduces the maintenance cost of the device, and at the same time ensures the long-term stable power supply of the battery pack 603, ensuring the continuous effectiveness of the early warning function.

[0029] In an exemplary embodiment, see Figure 3 The float 3 includes two hemispherical shells 301, which are connected by sealant.

[0030] Specifically, the detachable structure of the two hemispherical shells 301 facilitates the installation, inspection, and replacement of internal components, solving the problem of difficult maintenance of internal components in the integral float 3; the adhesive bonding method can achieve seamless sealing at the joint of the hemispherical shells 301, preventing external water and moisture from entering the accommodating cavity, avoiding short circuits or corrosion of internal electrical components, significantly improving the waterproof performance and overall structural strength of the float 3, extending the service life of the float 3, and making it suitable for the humid and water-rich harsh environment of water conservancy construction.

[0031] In an exemplary embodiment, see Figure 3 The limiting ring 302 and the float 3 are connected by adhesive sealant.

[0032] Specifically, the sealant bonding can eliminate the gap at the connection between the limiting ring 302 and the float 3, preventing water from seeping into the float 3 through the gap and further enhancing the overall waterproof performance of the float 3. At the same time, the bonding strength of the sealant can ensure a firm connection between the limiting ring 302 and the float 3, preventing the limiting ring 302 from falling off when the float 3 moves up and down along the guide rod 4, ensuring the stability of the guiding effect of the limiting ring 302 on the float 3, preventing the float 3 from deviating from the preset movement trajectory, and ensuring the accuracy of the early warning monitoring.

[0033] In an exemplary embodiment, a waterproof coating is filled between the indicator light 5 and the hemispherical housing 301.

[0034] Specifically, the waterproof coating can fill the tiny gap between the indicator light 5 and the hemispherical outer shell 301, blocking the path of water from the installation part of the indicator light 5 into the interior of the float 3, further improving the waterproof level of the float 3; at the same time, the waterproof coating can also protect the installation structure of the indicator light 5, reducing the erosion of the connection between the indicator light 5 and the outer shell by rainwater and mud, preventing the indicator light 5 from being damaged by short circuit due to water ingress or structural loosening, ensuring the normal operation of the indicator light 5 in a long-term humid and watery environment, and ensuring the stable output of the warning signal.

[0035] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.

[0036] The present application has been described in a relatively specific and detailed manner above through general descriptions and specific embodiments. It should be understood that, based on the technical concept of the present application, several conventional adjustments or further innovations can be made to these specific embodiments; however, as long as they do not depart from the technical concept of the present application, the technical solutions obtained by these conventional adjustments or further innovations also fall within the protection scope of the claims of the present application.
