Description

Technical Field

[0001] This application relates to the technical field of mountain engineering, and particularly to a protective device for a new type of mountain impounding project. Background Technique

[0002] A mountain impounding project refers to the process of impounding, guiding, discharging, protecting, and utilizing water resources by using the geographical conditions of the mountain. During the construction of a mountain impounding project, relevant safety regulations need to be strictly implemented, and necessary safety equipment and tools need to be equipped to protect the safety of the construction site.

[0003] A passive mountain protection net is a protective device used for slope protection in a mountain impounding project. The protection surface of this passive mountain protection net is made of steel wires. When in use, the protection net is installed on the mountain, and the falling rocks on the mountain are prevented from falling by the protection net, so as to form a surface protection for the area protected by the protection net and enhance the construction safety of the mountain impounding project.

[0004] However, in practical applications, the above-mentioned passive mountain protection net still has deficiencies. Specifically, the existing passive mountain protection net is mainly made of steel wires, and the mesh aperture of the protection net made of steel wires is relatively large, which can only block large-particle mountain rocks and cannot block small-particle mountain rocks or gravel. This results in that during the construction process, small-particle mountain rocks or gravel are likely to fall from the mesh holes, thus posing a safety risk to the construction personnel in the area protected by the protection net and being not conducive to use. Content of the Utility Model

[0005] In order to solve the problem that the mesh aperture of the existing passive mountain protection net is relatively large, which can only block large-particle mountain rocks and cannot block small-particle mountain rocks or gravel, resulting in certain safety risks still existing during the use of the protection net, this application provides a protective device for a new type of mountain impounding project.

[0006] A protective device for a new type of mountain impounding project provided by this application adopts the following technical solution:

[0007] A protective device for a new type of mountain impounding project includes a main body frame. One end of the main body frame is provided with a first connection component for fixing the main body frame on the mountain. The other end of the main body frame is installed with a stay cable. One end of the stay cable away from the main body frame is provided with a second connection component for connecting the stay cable to the mountain. There is an included angle between the stay cable and the main body frame. A first protection net for blocking large-particle mountain rocks and a second protection net for blocking small-particle mountain rocks and gravel are installed on the main body frame.

[0008] By adopting the above technical solution, during use, the main body frame is fixed on the mountain body through the first connection component, and then the anchor rope is fixed on the mountain body through the second connection component. Thus, the anchor rope provides a pulling force to the end of the main body frame far from the mountain body, thereby increasing the stability of the main body frame fixed on the mountain body. During use, through the combined action of the first protective net and the second protective net, the interception of large-particle mountain stones, small-particle mountain stones, and crushed stones is achieved, thereby improving the safety protection effect of the overall protective equipment and further ensuring the construction safety of the mountain project.

[0009] Preferably, the main body frame includes an outer frame body, a base fixed at one end of the outer frame body, and a plurality of main keels arranged inside the outer frame body. The plurality of main keels are distributed in a crosswise manner and are fixed on the outer frame body. The first connection component is arranged on the base. One end of the anchor rope is arranged at the end of the outer frame body far from the base. Both the first protective net and the second protective net are arranged on the outer frame body.

[0010] By adopting the above technical solution, during use, through the crosswise arrangement of a plurality of main keels and in combination with the outer frame body, the overall structural strength of the combined main body frame is higher, thereby increasing the bearing capacity of the main body frame and further improving the safety protection performance of the protective equipment.

[0011] Preferably, the first protective net is located between the second protective net and the main keels, and the second protective net is detachably connected to the outer frame body.

[0012] By adopting the above technical solution, during use, when there is a phenomenon of mountain collapse causing mountain stones and water to fall downward, the large-particle mountain stones can be intercepted first by the main keels and the first protective net, preventing the large-particle mountain stones from directly falling on the second protective net and affecting the service life of the second protective net. At the same time, the small-particle mountain stones and crushed stones pass through the mesh holes of the first protective net and fall on the second protective net, and the second protective net intercepts the small-particle mountain stones and crushed stones, thereby avoiding the situation of small-particle mountain stones and crushed stones falling from a height. The detachable connection of the second protective net facilitates the construction personnel to replace the second protective net and ensures the protective effect of the second protective net.

[0013] Preferably, a plurality of hooks are fixed on the outer frame body, and the second protective net is suspended on the hooks.

[0014] By adopting the above technical solution, during use, the second protective net is detachably connected to the outer frame body through the hooks, which is convenient for the assembly and replacement of the construction personnel on the premise of ensuring the protective function of the second protective net.

[0015] Preferably, the first connection component includes a plurality of expansion bolts, and the base is detachably connected to the mountain body through the expansion bolts.

[0016] By adopting the above technical solution, when in use, the main frame is detachably connected to the mountain body through expansion bolts, so that after the construction is completed, it is convenient for the construction personnel to disassemble the main frame for secondary use.

[0017] Preferably, an energy dissipation rope loop is arranged on the anchor rope.

[0018] By adopting the above technical solution, when in use, the energy dissipation rope loop effectively absorbs and slows down the impact force on the anchor rope, with simple structure, strong adaptability and low cost.

[0019] Preferably, the second connection assembly includes a turnbuckle and an anchor hook fixed on the mountain body, and the anchor rope is connected to the anchor hook through the turnbuckle.

[0020] By adopting the above technical solution, when in use, through the combined use of the turnbuckle and the anchor hook, the quick connection between the anchor rope and the mountain body is realized, which is simple and convenient to use, and at the same time is convenient for the construction personnel to adjust the tension of the anchor rope.

[0021] Preferably, a vibration alarm is further installed on the main frame.

[0022] By adopting the above technical solution, when in use, when large particle mountain stones fall onto the first protective net, it will cause the first protective net and the main frame to vibrate, and then the vibration alarm detects the vibration and alarms to remind the construction personnel, so as to leave enough escape time for the construction personnel and increase the construction safety of the mountain project.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. When in use, by installing the first protective net and the second protective net on the main frame, when in use, through the combined use of the first protective net and the second protective net, large particle mountain stones, small particle mountain stones and crushed stones can be blocked, so as to increase the safety protection of the protection equipment and ensure the construction safety of the mountain project;

[0025] 2. Through the combined use of the first connection assembly and the second connection assembly, the main frame is detachably connected to the mountain body, so as to facilitate disassembly and reuse after subsequent construction is completed, and it is more convenient to use;

[0026] 3. When in use, by installing a vibration alarm on the main frame, when the mountain stones fall onto the first protective net, it will cause the main frame to vibrate slightly, and then the vibration alarm reminds the construction personnel below the protection equipment that there are falling stones, so as to ensure that the construction personnel have enough time to escape.

[0033] The embodiment of the present application discloses a protective equipment for a new type of mountain impounding project.

[0034] Referring to Figure 1 and Figure 2 , a protective equipment for a new type of mountain impounding project includes a horizontally placed main body frame 1, and the main body frame 1 is composed of an outer frame body 11, a base 12 and a main keel 13. The outer frame body 11 is a rectangular frame structure formed by welding four square steel pipes, and the main keel 13 is a cross-shaped structure formed by welding four square steel pipes. The main keel 13 is welded and fixed inside the outer frame body 11. In this embodiment, the steel pipes for making the outer frame body 11 and the main keel 13 are all selected with a width of 100 mm, a height of 100 mm, and a wall thickness of 5 mm.

[0035] Referring to Figure 1 and Figure 2 , the base 12 is formed by three square steel pipes and three connecting plates welded on the square steel pipes. The base 12 is integrally welded and fixed at one end of the outer frame body 11 in the width direction. Among them, the three square steel pipes are arranged at equal intervals along the length direction of the outer frame body 11. A first connection component 2 is further arranged on the base 12, and the first connection component 2 is used to fix the base 12 on the mountain body; during use, by opening an installation hole on the mountain body and inserting the three square steel pipes into the installation hole until the connecting plate abuts against the mountain body, the square steel pipes can be fixed on the mountain body through the first connection component 2, so as to realize fixing the base 12 on the mountain body.

[0036] Reference Figure 1 and Figure 2 Figure 2 , the first connecting component 2 includes a plurality of expansion bolts 21. In this embodiment, the expansion bolts 21 are preferably set as M8 type, and four M8 expansion bolts 21 are arranged on each connecting plate to ensure the connection stability between the base 12 and the mountain body; during use, through the combined action of multiple expansion bolts 21, the main frame 1 is stably fixed on the mountain body, and at this time, the main frame 1 is vertically arranged on the mountain body as a whole. At the same time, the connection method using expansion bolts 21 is more convenient for construction workers to remove the main frame 1 after construction is completed, which is beneficial to the secondary use of the protection equipment.

[0037] Reference Figure 1 and Figure 2 Figure 2 , a stay rope 3 is arranged at one end of the outer frame body 11 away from the base 12. One end of the stay rope 3 is wound and fixed on the outer frame body 11, and a second connecting component 4 is arranged at the other end of the stay rope 3. The second connecting component 4 is used to fixedly connect the end of the stay rope 3 away from the outer frame body 11 to the mountain body. And when the stay rope 3 is fixed on the mountain body, there is an included angle between the stay rope 3 and the outer frame body 11. In this embodiment, the included angle between the stay rope 3 and the outer frame body 11 is preferably set to forty-five degrees; during use, the stay rope 3 provides a pulling force to the end of the outer frame body 11 away from the base 12, thereby increasing the stability of the main frame 1 installed on the mountain body.

[0038] Reference Figure 2 and Figure 3 Figure 3 , the second connecting component 4 includes a turnbuckle 41 and an anchor hook 42. Among them, a part of the anchor hook 42 is inserted and fixed in the mountain body, and a hook ring is formed between the other part of the anchor hook 42 and the outer wall of the mountain body. One end of the turnbuckle 41 is fixedly connected to the stay rope 3, and the other end of the turnbuckle 41 is hooked on the anchor hook 42; during use, first fix the anchor hook 42 on the mountain body, then connect the stay rope 3 to the anchor hook 42 through the turnbuckle 41, and then adjust the tightness of the stay rope 3 through the turnbuckle 41, so as to ensure that the stay rope 3 can provide an appropriate pulling force to the main frame 1.

[0039] Reference Figure 1 and Figure 2, a plurality of energy dissipation rope loops 8 are also installed on the tie-down rope 3. In this embodiment, the energy dissipation rope loop 8 is preferably set as a steel wire rope pressure relief loop, and one pressure relief loop is arranged on each tie-down rope 3. The pressure relief loop is mainly composed of an annular steel pipe and a fixing member. The annular steel pipe is spirally wound around at least one turn in a spiral spring shape. Both ends of the steel pipe are open and cross on a longitudinal diameter line on the spiral side surface, and extend forward on both sides in the plane where the tangent line of the spiral cross-section is located. The fixing member is a sleeve, and the fixing member fixes the steel pipe spiral and the steel pipe end at the cross of both ends of the steel pipe. When in use, when the tension of the tie-down rope 3 connected to the energy dissipation rope loop 8 reaches a certain degree, the energy dissipation rope loop 8 is activated and absorbs energy through deformation displacement, so as to achieve overload protection.

[0040] Refer to Figure 1 and Figure 2 , a first protective net 5 is fixed on the bottom surface of the outer frame body 11. In this embodiment, the first protective net 5 is preferably made of a steel wire rope net. The mesh shape of the first protective net 5 can be set as a circle, a polygon, etc. In this embodiment, the mesh shape of the first protective net 5 is preferably set as a rhombus. A plurality of hooks 7 are also welded and fixed on the bottom surface of the outer frame body 11. In this embodiment, the hooks 7 are preferably set as four, and the hooks 7 are made of steel. The four steel hooks 7 are respectively located at the four corners of the bottom surface of the outer frame body 11.

[0041] Refer to Figure 2 and Figure 4 , a second protective net 6 is also arranged below the first protective net 5. In this embodiment, the second protective net 6 is preferably set as a two-thousand-mesh dense mesh safety net, and steel rings are formed on the second protective net 6. When in use, the second protective net 6 is hung below the outer frame body 11 by hanging the steel rings on the steel hooks 7. Thus, through the combined use of the first protective net 5 and the second protective net 6, the blocking effect on large-particle mountain stones, small-particle mountain stones and gravel is achieved.

[0042] Refer to Figure 1 and Figure 2 , a vibration alarm 9 is also installed on the outer frame body 11 and the main keel 13 by bolts. In this embodiment, the vibration alarm 9 is preferably set as three, two of which are located at both ends of the outer frame body 11 in the length direction, and the other vibration alarm 9 is located at the center position of the top surface of the main keel 13. When in use, when large-particle mountain stones, small-particle mountain stones or gravel fall on the first protective net 5 or the second protective net 6, under the influence of gravity, the first protective net 5 or the second protective net 6 will vibrate, and at the same time drive the entire main body frame 1 to vibrate. At this time, the vibration alarm 9 can detect the vibration force on the main body frame 1 and send out an alarm signal, so as to remind the construction workers below the protection equipment that mountain stones have fallen, thereby ensuring that the construction workers have enough time to escape.

[0043] Refer to Figure 1, in this embodiment, the alarm form of the vibration alarm 9 can adopt the combined action of an alarm lamp and sound to ensure that the construction personnel can receive the alarm signal in time.

[0044] The implementation principle of the embodiment of this application is as follows: During use, first, the construction personnel open a plurality of installation holes for installing the expansion bolts 21, the bases 12, and the anchoring hooks 42 on the mountain body to be protected. Then, the anchoring hooks 42 are installed in the installation holes. After that, the main frame 1 is moved to the corresponding installation position by hoisting. Then, the base 12 is inserted into the corresponding installation hole, and the base 12 is fixed on the mountain body through the expansion bolts 21 to complete the preliminary fixation of the main frame 1. After that, one end of the tension cable 3 is wound and connected to one end of the main frame 1, and the other end of the tension cable 3 is hooked on the anchoring hook 42 through the turnbuckle 41. Then, the tension of the tension cable 3 is adjusted to an appropriate value through the turnbuckle 41 to complete the secondary fixation of the main frame 1. After that, the second protection net 6 can be loaded on the main frame 1. Finally, the signal of the vibration alarm 9 is turned on to complete the overall installation of the protection device. During use, the large particle mountain stones are blocked by the first protection net 5, the small particle mountain stones and gravel are blocked by the second protection net 6, and the construction personnel are reminded to escape in time through the vibration alarm 9, thereby enhancing the safety protection effect of the overall protection device. At the same time, the entire protection device is detachable, which is convenient for the construction personnel to disassemble and transfer it to other positions after the construction is completed, thus facilitating secondary use.

[0045] The above are all the preferred embodiments of this application. It does not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
