[0002] In the water conservancy system, water canals are key infrastructure for the transportation and distribution of water resources. The quality of their construction and maintenance directly affects regional agricultural irrigation, ecological water replenishment, and the safety of residents' water use. In the construction and daily operation and maintenance of water canals in water conservancy projects, interception operations are the core means to achieve scientific allocation of water resources and ensure the stable operation of water canals.

[0003] Chinese Patent No. CN207092041 U discloses a water flow interception and diversion device for hydraulic construction, including an installation plate with a first opening. Two pairs of columns are installed under the installation plate, and a base plate is installed under each column.

This device can replace manual water release, control the flow rate to prevent damage to rice seedlings at the water inlet, and provide illumination for observing the water flow at night.

[0004] In water conservancy projects, the shapes and sizes of various water channels vary according to their uses. This device and similar devices cannot be used to flexibly and effectively block and intercept water according to the shape of the water channel in actual use. This problem seriously affects the applicability and work efficiency of the equipment in scenarios such as water channel maintenance, water volume regulation, and emergency rescue, and cannot fully meet the diverse actual needs of water conservancy projects. Utility Model Content

[0005] The main purpose of this utility model is to provide a water conservancy construction interception device that can effectively solve the problems mentioned above.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A water conservancy construction interception device includes a water channel and an expansion bladder. The expansion bladder is limited and sealed within the water channel by a deployment component. A floating bladder is glued to the top of the expansion bladder. A gas-liquid supply component is provided between the expansion bladder and the floating bladder on one side along the upstream direction of the water channel. A pressure relief component is provided on one end of the floating bladder along the downstream direction of the water channel.

[0008] Preferably, the deployment assembly includes multiple straps and multiple counterweights, with the multiple counterweights being equidistantly glued to the bottom of the inner cavity of the inflatable bladder, and the multiple straps being symmetrically glued in pairs to the two sides of the top of the floating bladder away from the center.

[0009] Preferably, multiple tension steel rings are fixedly connected through each of the multiple straps.

[0010] Preferably, the gas-liquid supply assembly includes a connecting plate and multiple air supply hoses. The connecting plate is fixedly installed on the lower side of the end face of the inner cavity of the expansion bladder in the height direction. Multiple water supply pipes are respectively installed through the end face of the connecting plate in the height direction, and the input ends of the multiple water supply pipes are all located on the side close to the upstream direction of the water channel.

[0011] Preferably, multiple air supply hoses are fixedly connected and installed between the top of the expansion bladder and the upper side of the end face in the height direction of the floating bladder, and multiple connecting sleeves are fixedly connected and installed on the end face of the multiple air supply hoses extending into the expansion bladder.

[0012] Preferably, multiple connecting ring frames are fixedly connected to the upper ports of the multiple connecting sleeves, multiple guide rods are slidably connected to the inner surfaces of the multiple connecting ring frames, and multiple sealing floats are fixedly connected to the bottom ends of the multiple guide rods. The outer wall diameter of the multiple sealing floats is adapted to the wall diameter of the lower ports of the multiple connecting sleeves.

[0013] Preferably, the pressure relief assembly includes a sleeve disposed on the floating bag in the downstream direction of the water channel. The sleeve is fixedly installed through the end face of the floating bag in the height direction. One end of the sleeve penetrating into the floating bag is open.

A piston is slidably connected to the inner surface of the sleeve. A spring is placed in the inner cavity of the sleeve, and the two ends of the spring abut against the piston and the end face of the inner cavity of the sleeve, respectively.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model utilizes the flexible properties of the expansion bladder to adapt to the inner wall of water channels of different shapes.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1-5 As shown, a water conservancy construction interception device includes a water channel 1 and an expansion bag 2. The expansion bag 2 is limited and sealed in the water channel 1 by a deployment component 6. A floating bag 3 is glued to the top of the expansion bag 2. A gas-liquid supply component 4 is jointly provided between the expansion bag 2 and the floating bag 3 on one side along the upstream direction of the water channel 1. A pressure relief component 5 is provided on one end of the floating bag 3 along the downstream direction of the water channel 1.

[0025] In actual implementation, this solution uses a novel arrangement of components 6 to allow the expansion bag 2 to quickly sink to the bottom of the water, enabling it to expand rapidly by filling with water. This avoids the problem of the expansion bag 2 floating on the water surface and being difficult to expand due to its material properties. In addition, the arrangement of components 6 can locate the position of the device, preventing the expansion bag 2 from being washed away by the water flow in the early stages of filling.

[0026] The expansion bladder 2 utilizes its flexible properties to adapt to the inner wall of water channels of different shapes. The expansion bladder 2 is automatically filled with water and expands to seal the channel, without the need for additional power equipment. It can tightly seal water channels of different shapes, enhancing its applicability. After water enters the expansion bladder 2, the air inside the expansion bladder 2 is squeezed out and enters the floating bladder 3 through the gas-liquid supply component 4, so that the floating bladder 3 can float on the water surface. The floating bladder 3 pulls the expansion bladder 2 upward, which is more conducive to the expansion of the expansion bladder 2 after it is filled with water.

[0027] The floating bag 3 is smaller than the expansion bag 2. Therefore, in order to prevent the floating bag 3 from bursting due to high pressure after the air in the expansion bag 2 enters the floating bag 3, the high-pressure gas in the floating bag 3 is released in a metered manner through the pressure relief component 5 set on the floating bag 3.

[0028] Specifically, the deployment component 6 includes multiple straps 61 and multiple counterweights 62. The multiple counterweights 62 are glued together at equal intervals on the bottom of the inner cavity of the expansion bladder 2, and the multiple straps 61 are glued together symmetrically in pairs on both sides of the top of the floating bladder 3 away from the middle.

[0029] Multiple tension steel rings 611 are connected and fixedly threaded through multiple straps 61;

[0030] Multiple positioning rods are driven into both sides of the bank of the water channel 1. Multiple straps 61 symmetrically installed on both sides of the top of the floating bag 3 are tied to the positioning rods. Then, after the expansion bag 2 is placed in the water channel 1, the weight of multiple counterweights 62 at the bottom of the inner cavity of the expansion bag 2 will allow the expansion bag 2 to slowly sink to the bottom of the water.

[0031] Furthermore, the gas-liquid supply assembly 4 includes a connecting plate 41 and multiple air supply hoses 42. The connecting plate 41 is fixedly installed on the lower side of the end face of the inner cavity of the expansion bladder 2 in the height direction. Multiple water supply pipes 411 are respectively installed through the end face of the connecting plate 41 in the height direction. The input ends of the multiple water supply pipes 411 are all located on the side near the upstream direction of the water channel 1.

[0032] Multiple air supply hoses 42 are fixedly connected and installed between the top of the expansion bag 2 and the upper side of the end face in the height direction of the floating bag 3. Multiple air supply hoses 42 extend into the end face of the expansion bag 2 and are fixedly connected and installed with multiple connecting sleeves 43.

[0033] Multiple connecting sleeves 43 are fixedly connected to the upper ports of multiple connecting ring frames 44, and multiple guide rods 45 are slidably connected to the inner surfaces of multiple connecting ring frames 44. Multiple sealing floats 46 are fixedly connected to the bottom ends of multiple guide rods 45, and the outer wall diameter of multiple sealing floats 46 is adapted to the wall diameter of the lower ports of multiple connecting sleeves 43.

[0034] After the expansion bag 2 is put into the water, when the water flows downstream along the upstream direction of the water channel 1, it is poured into the expansion bag 2 through multiple connecting plates 41, which causes the expansion bag 2 to expand. This allows the expansion bag 2 to fit and match the cross-sectional shape of the water channel 1, thereby achieving the function of interception.

[0035] As water enters the expansion bladder 2, the air inside is compressed by the water flow and enters the floating bladder 3 through the connecting sleeve 43 and the air supply hose 42, thereby causing the floating bladder 3 to expand. The expansion of the floating bladder 3 causes the floating bladder 3 to float on the water surface, which in turn pulls the upper part of the expansion bladder 2 upwards, thereby allowing the water flow to more effectively fill the inner cavity of the expansion bladder 2.

[0036] When the water level in the expansion bladder 2 reaches the bottom of the sealing float 46, the sealing float 46 floats upward and seals the connecting sleeve 43, thereby preventing water from the expansion bladder 2 from entering the floating bladder 3 and affecting the floating effect of the floating bladder 3.

[0037] Furthermore, the pressure relief component 5 includes a sleeve 51, which is disposed on the floating bag 3 in the downstream direction of the water channel 1. The sleeve 51 is fixedly installed through the end face of the floating bag 3 in the height direction. One end of the sleeve 51 that penetrates into the floating bag 3 is open. Multiple air vents 55 are arranged in a ring array on the outer surface of the sleeve 51 that protrudes into the floating bag 3. A stop ring 52 is fixedly connected to the inner port of the sleeve 51. A piston 53 is slidably connected to the inner surface of the sleeve 51. A spring 54 is placed in the inner cavity of the sleeve 51. The two ends of the spring 54 abut against the piston 53 and the inner end face of the sleeve 51, respectively.

[0038] When the air pressure inside the expansion bladder 2 is greater than the thrust of the spring 54 on the piston 53, the high-pressure gas pushes the piston 53 to squeeze the spring 54 in the opposite direction. After the piston 53 slides and squeezes the spring 54, multiple air outlets 55 leak out, and the high-pressure gas is released to the outside through multiple air outlets 55.

[0039] It should be noted that the standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the specification and drawings can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
