Description

Technical Field

[0001] The utility model relates to the technical field of water area emergency rescue, in particular to an obstacle combination structure for water area rescue. Background Art

[0002] Affected by extreme weather, the number of people trapped in floods has increased significantly, water rescue tasks have become increasingly arduous, and the rescue situation has become increasingly severe. For rescue personnel, traditional water rescue simulation training is limited to simulating rescue training such as drowning and flooding in natural river waters. Training in natural venues such as rivers is very dangerous, and emergency rescue units generally conduct less water rescue training. Therefore, water rescue simulation facilities have emerged;

[0003] In order to simulate various flow patterns in a waterway, obstacles need to be set up in the waterway. Different combinations of obstacles will form rapids of different forms.

[0004] For example, the patent publication number CN218471455U, “A torrent waterway structure”, sets obstacles in the waterway to form various intense flow channels;

[0005] However, existing obstacles usually adopt circular or square hollow cylindrical structures; when the circular hollow cylindrical structure obstacles are spliced, the lines are connected to each other, resulting in a small contact surface, and the small contact surface has a poor sealing effect, which makes it easy for water to pass through and reduces the effect of blocking water flow; when the square hollow cylindrical structure obstacles are spliced, the side that blocks the water flow is spliced ​​to form a plane wall, which has a small overall obstruction and is not easy to generate too much turbulence or eddy current. In addition, the hollow design of the obstacle body leads to its low strength. Utility Model Content

[0006] The purpose of the utility model is to provide an obstacle combination structure for water rescue to solve the problems raised in the above background technology.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] An obstacle combination structure for water rescue, wherein the obstacle combination structure is arranged in a waterway;

[0009] The obstacle combination structure includes a plurality of groups of obstacles spliced ​​together;

[0010] The obstacle comprises a base, a column arranged on the base, and an obstacle body sleeved outside the column, and the horizontal outer contour section of the obstacle body is a regular polygon with more than six sides;

[0011] The obstacle body is a shell structure with a hollow interior;

[0012] The obstacle body is penetrated with a transverse water-permeable hole in the horizontal direction, and the obstacle body is penetrated with a vertical water-permeable hole in the vertical direction.

[0013] Preferably, the base is arranged to be inclined downward at both the front and rear sides along the water flow direction.

[0014] Preferably, a through hole is provided on the base, and the lower end of the column is inserted into the corresponding through hole.

[0015] Preferably, the top wall of the obstacle body is raised to form a positioning protrusion, and the bottom wall of the obstacle body is concave to form a positioning recess, and the positioning protrusion and the positioning recess are matched.

[0016] Preferably, the horizontal cross-section of the positioning protrusion and the positioning recess is in a "cross" shape.

[0017] Preferably, when the upper and lower adjacent obstacle bodies are connected as a whole through the positioning protrusions and the positioning recesses, the vertical water-permeable holes correspond one to one and are aligned up and down.

[0018] Preferably, the horizontal outer contour cross-section of the obstacle body is a regular hexagon.

[0019] Preferably, the obstacle is made of linear low-density polyethylene by rotational molding, and the thickness of the obstacle is 8 mm.

[0020] Preferably, the transverse water-permeable holes are opened in the lower middle part of the obstacle body.

[0021] Preferably, the obstacle combination structure also includes a pull rope, and the vertical water-permeable holes of more than two obstacle bodies in the vertical direction are passed through and fixed into a whole by the same pull rope, and / or the horizontal water-permeable holes of more than two obstacle bodies in the horizontal direction are passed through and fixed into a whole by the same pull rope.

[0022] Compared with the prior art, the beneficial effects of the utility model are:

[0023] The utility model adopts an obstacle body with a hollow cylindrical hexagonal structure. When two adjacent obstacle bodies are spliced, the surfaces are abutted against each other to improve the sealing effect. When a row of obstacle bodies are spliced, a side that cooperates with the water flow forms an uneven wall structure. The uneven wall structure has a larger overall obstruction and is more likely to produce turbulence or eddy effects.

[0024] Due to the hollow design inside the obstacle body, the impact force when the user hits the obstacle body is small, reducing the harm to the user; the horizontal water-permeable holes are conducive to underwater water passing through the obstacle body to increase the water speed and reduce the buoyancy of the obstacle body, and will not hinder the flow rate on the water surface; at the same time, the horizontal water-permeable holes and the vertical water-permeable holes are filled with water to improve the overall strength of the hollow obstacle body.

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Example:

[0034] A combination structure of obstacles for water rescue, such as Figures 1-4 As shown, it includes an inlet pool 1, a water channel 2 and an outlet stilling pool 3. The water in the inlet pool 1 flows to the outlet stilling pool 3 through the water channel 2. An obstacle combination 4 is arranged in the water channel 2 to form various violent flow channels such as boiling flow, frowning flow, V-shaped flow, tumbling flow, etc.

[0035] like Figure 4 As shown, the obstacle combination 4 includes a plurality of obstacles spliced ​​together, and the plurality of obstacles can be spliced ​​together to form obstacle combinations 4 of different shapes according to different violent flow channels.

[0036] The obstacle is made of linear low-density polyethylene through rotational molding process. It has a hollow interior, a thickness of 8mm, and a regular hexagonal horizontal cross-section.

[0037] The obstacle includes a base 41, a column 42 and an obstacle body 43;

[0038] The base 41 is fixed to the bottom plate of the waterway 2 by fastening components such as bolts. The base 41 is inclined at both sides along the front and rear of the water flow to reduce the impact on the underwater flow velocity.

[0039] A plurality of circular through holes are vertically opened on the top of the base 41, and the outer diameter of the column 42 just matches the inner diameter of the through hole, so that the lower end of the column 42 can be inserted into the through hole of the base 41 and then fixed with glue; the length of the column 42 has various specifications.

[0040] A through hole 431 is vertically opened in the middle of the obstacle body 43, and multiple obstacle bodies 43 are arranged and sleeved on the outer wall of the same column 42 through the through hole 431; a plurality of vertical water-permeable holes 45 are vertically opened in the obstacle body 43 and evenly distributed around the axis of the through hole 431; a horizontal water-permeable hole 44 is horizontally opened in the lower part of the obstacle body 43.

[0041] The transverse water holes 44 are arranged in the middle and lower part of the obstacle body 43, so that the water flow velocity in the upper part of the obstacle body 43 is much smaller than the water flow velocity in the middle and lower part; when the arrangement direction of the transverse water holes 44 is consistent with the water flow direction, it is beneficial for underwater water to pass through the obstacle body 43 to increase the water velocity, and will not hinder the flow velocity of the water surface. The transverse water holes 44 can also be used to connect the pull rope. The transverse water holes 44 on several horizontally connected obstacle bodies 43 are aligned with each other, and the pull rope passes through the aligned transverse water holes 44 to achieve the fixed connection of several obstacle bodies 43.

[0042] The vertical water-permeable holes 45 allow water to pass through the obstacle body 43, which helps to reduce the buoyancy of the obstacle body 43. The vertical water-permeable holes 45 can also be used to connect a pull rope. By passing the pull rope through the vertical water-permeable holes 45 of multiple obstacle bodies 43, the multiple obstacle bodies 43 can be fixedly connected together. At the same time, one end of the pull rope can also be fixed to the side wall of the waterway 2.

[0043] In order to prevent the user from falling into the water and colliding with the obstacle body 43 during training and causing injuries, the obstacle body 43 is designed to be hollow inside to reduce the impact force; the horizontal water-permeable holes 44 and the vertical water-permeable holes 45 allow water to pass through, and a number of horizontally and vertically arranged reinforcing ribs are designed inside the obstacle body 43 to prevent the obstacle body 43, which is large in size, thin in thickness and hollow inside, from being damaged upon being hit.

[0044] likeFigure 3 As shown, the horizontal cross-section outer contour of the obstacle body 43 is a regular hexagon; when two adjacent obstacle bodies 43 are horizontally spliced, they are face-to-face abutted, which makes the abutment and sealing effect between the two obstacle bodies 43 better, preventing water from flowing through the gap between the two adjacent obstacle bodies 43 and reducing the effect of blocking water flow. Figure 4 As shown, a side wall formed by a plurality of obstacle bodies 43 arranged in a line is a non-planar uneven wall structure. The uneven wall will increase the resistance of the water flow. The irregular structure of the wall will cause the water flow to more easily form turbulence or eddies during the flow, which facilitates the formation of various intense flow channels in the waterway 2.

[0045] like Figure 3 As shown, the top of the obstacle body 43 forms a positioning protrusion 46 with a "cross"-shaped profile that protrudes upward, and the bottom of the obstacle body 43 is recessed to form a positioning recessed portion with a "cross"-shaped profile. The two upper and lower adjacent obstacle bodies 43 are positioned and prevented from circumferential rotation through the cooperation of the positioning protrusion 46 and the positioning recessed portion, while also ensuring that the vertical water-permeable holes 45 arranged upper and lower correspond to each other and are aligned with each other; due to different intense flow channels, obstacle combinations 4 of different heights need to be designed; the obstacle body 43 has a variety of height specifications, and a number of obstacle bodies 43 of different heights can be spliced ​​and sleeved on the same column 42 as needed to form an obstacle combination 4 of required height.

[0046] The base 41 , the column 42 and the obstacle body 43 can be bonded and fixed together into one body by glue.
