Embodiment

[0023] The above scheme will be further described in combination with specific embodiments. It should be understood that these embodiments are used to illustrate the present application rather than limit the scope of the present application. The implementation conditions used in the embodiments can be further adjusted according to the specific conditions of the manufacturer, and the implementation conditions not mentioned are usually the conditions in the conventional experiments.

[0024] In one specific embodiment, a buoyant underwater blasting protection net is provided, which, like the prior art, includes a top net 1 and a side net 2 connected to the side edges thereof, to achieve the surrounding of the blasting point. Unlike the prior art, in this example, the top net 1 and the side net 2 are not fixed to the riverbed bottom by ropes or pulled on the water surface or underwater by ropes.

[0025] In use, the top net 1 and the side net 2 can form a hood-shaped structure with the opening downward, so as to be hooded above the blasting point.

[0026] In this example, the specific implementation of installing the protection net in the water is that a plurality of first floating pulls 1.1 are arranged on the top of the top net 1, and a plurality of first floatings 1.2 are detachably installed on the top of the top net 1, and a plurality of weight installation rods 1.3 are arranged on the top of the top net 1, and a plurality of upper weight blocks 1.4 are detachably installed on the top of the top net 1; in addition, a plurality of bottom rods 2.1 are arranged on the bottom of the side net 2, which can keep the bottom of the side net 2 in an expanded state, and a plurality of lower weight blocks 2.2 are arranged on the bottom rods 2.1, and a second floating pull 2.3 is connected to the top of the bottom rod 2.1, and a plurality of second floatings 2.4 are detachably installed on the top of the second floating pull 2.3.

[0027] In order to realize the quick disassembly of the float and the pull, the preferred connection structure of the two is provided in this example, the hard rod body is arranged on the top of the first float pull 1.1 and the second float pull 2.3, the first float 1.2 and the second float 2.4 can be sleeved on the rod body, and the baffle b can be slidably installed on the rod body along the axis line, the float is positioned axially against the baffle b, and then different numbers of floats can be sleeved on the rod body, and only the baffle b needs to be fixed.

[0028] On this basis, in order to further improve the convenience of float disassembly, the first float 1.2 and the second float 2.4 are provided with openings on one side, and are installed on the hard rod body from the side through the openings. Therefore, the inconvenience of disassembling the baffle b from the rod body is avoided.

[0029] In addition, in this example, in order to facilitate the disassembly of the float, the float is kept in a floating state or close to the water surface position, and the first float pull 1.1 and the second float pull 2.3 are preferably arranged to be adjustable in length. Since the float pull in this example uses a rope, the length of the rope can be adjusted, and it is also suitable for use in rivers of different depths.

[0030] In this example, the first float 1.2 and the second float 2.4 are made of PVC material or have a hollow plastic cavity structure. The upper counterweight 1.4 and the lower counterweight 2.2 are made of concrete blocks or metal blocks.

[0031] In use, the first float 1.2 can drive the top net 1 to float, and the upper counterweight 1.4 cooperates with the first float 1.2 to adjust the floating or suspension height of the top net 1 in the water, thereby adjusting the distance from the bottom of the side net 2 to the blasting point (usually contact), on the other hand, the two can also be used together to adjust the balance and inclination of the top net 1. When inclined, the bottom of the side net 2 can be arranged around the blasting point area of the inclined surface.

[0032] Similarly, the second float pull 2.3 and the lower counterweight 2.2 can expand or contract the bottom of the top net 1. It should be noted that the expansion or contraction is achieved by adjusting the number of the second float pull 2.3. Therefore, the size of the expansion of the bottom of the side net 2 can be adjusted.

[0033] In this example, the outer contour of the top net 1 and the side net 2 can be a polygonal convex table shape or a circular table shape, the main difference being the shape of the bottom rod 2.1. When it is a polygonal convex table shape, the bottom rod 2.1 is a straight rod, and when it is a circular table shape, the bottom rod 2.1 is a straight rod.

[0034] It should be noted that the protective net in this case is more suitable for use in small or no water flow river. In the river with larger water flow, a plurality of bottom pullers 2.6 can be arranged at the bottom end of the side net 2, and a counterweight block is fixed at the end of the bottom puller 2.6 or an anchor is used.

[0035] In this case, the top net 1 and the side net 2 can be an integrated structure or a two-body structure. Specifically, the two-body structure can be provided with a hard frame body 1a at the edge of the top net 1, and the side net 2 is connected to the edge body of the frame body 1a. Preferably, the side net 2 can be connected to the edge of the frame body 1a through the connecting ring 2.5. The connecting ring 2.5 can avoid damage to the connecting net body, and can facilitate the disassembly and assembly of the two, and is suitable for installation of side nets of different specifications and sizes. The first floating puller 1.1 and the counterweight mounting rod 1.3 are both installed on the top of the frame body 1a, so that the top net 1 can form a frame net plate structure that can float independently. The side net can be lifted in the water and has a certain supporting property, which can make the top of the protective net keep expanding and has a certain rigidity to facilitate the installation and fixation of the counterweight, thereby improving the balance and stability of the protective net in the water.

[0036] In addition, on this basis, in order to further improve the balance performance of the frame body 1a, a balance frame 3 is arranged at the top of the frame body 1a, and the end of the balance frame 3 extends outwardly from the frame body 1a, and a balance plate 3.1 is arranged at the extending end of the balance frame 3. The balance plates 3.1 are uniformly arranged around the hard frame body 1a. In this case, the balance plates 3.1 are placed outside the frame body 1a in the water, thereby increasing the stress range of the frame body.

[0037] In order to further improve the stress range of the frame body 1a in the water, the length of the end of the balance frame 3 extending outwardly from the frame body 1a can be adjusted, so that the balance plate 3.1 can be extended outwardly by adjusting.

[0038] On this basis, in order to further improve the stability of the bottom of the side net and realize the fixation of the bottom opening, the second floating puller 2.3 can be connected to the extending end of the balance frame 3. Specifically, the fixing can be realized by using the rope binding method or the rope clip.

[0039] Based on the above ideal embodiments according to the present application, through the above description, relevant personnel can make various changes and modifications without deviating from the technical idea of the present application. The technical scope of the present application is not limited to the contents in the specification, and must be determined according to the scope of claims.
