Description

Technical Field

[0001] This utility model relates to the field of flood control and disaster relief technology, and in particular to a ground-mobile pipe inflow infiltration cover device. Background Technology

[0002] During the flood season, river embankments face a serious threat of piping failure. In the early stages, piping involves a small amount of seepage and causes minor damage. However, as it progresses and a large amount of sand is carried away, it forms a concentrated, pipe-like seepage, which greatly threatens the safety of the embankment and can easily cause it to collapse in a short period of time. Therefore, emergency measures are needed to promptly seal the seepage channels and prevent it from developing and expanding further.

[0003] Emergency response methods for centralized piping mainly involve sealing the seepage channels. These methods include sealing the inlet and sealing or reducing pressure at the outlet. The most effective method is sealing the inlet, controlling the water flow's erosion and damage to the channel, maintaining its stability, and then further reinforcing it after the flood season. Currently, the simplest method for sealing the inlet is for rescue personnel to go into the water and stuff cotton wadding or straw rolls into the inlet. This method is quick and effective, but the safety of the rescue personnel cannot be guaranteed. Therefore, people have invented some sealing methods utilizing the water-swelling property of expanding resin, such as the ball bag method. A series of balls filled with expanding resin, ranging from small to large, are strung together at certain intervals. Under the action of the seeping water flow, the smaller balls enter the channel first, pulling the larger balls in succession. By filling the balls with water, their volume expands, thus sealing the channel. Some researchers have also designed the series of balls into an inverted triangular cone shape. The disadvantages of this method are that the leakage channels are complex in shape, making it difficult to ensure that the ball bag can smoothly enter the leakage channels. Secondly, if the ball bag is not large enough after expansion, there will still be leakage gaps in the channels, which will not achieve the sealing effect. Utility Model Content

[0004] This invention addresses the shortcomings of existing centralized pipeline-type piping sealing devices by providing a ground-mobile inlet covering device. A frame equipped with rollers pushes a covering membrane over the inlet and covers it, preventing water from flowing into the piping channel, maintaining the stability of the seepage channel, and ensuring the safety of river embankments during flood season.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A ground-mobile pipe inflow intrusion covering device includes a frame, crankshaft rollers, a pin device, a covering membrane, and a push rod. The frame is square, and the covering membrane is fixed to the bottom surface of the frame.

[0007] The crankshaft roller and pin device are fixed to the top surface of the frame, the push rod is hinged to the frame by a pin, and the pipe inflow cover device is configured as a trolley structure with a cover film.

[0008] Furthermore, the frame includes four frame beams, four corner braces, and four clamping strips;

[0009] Adjacent frame beams are connected and fixed together by brackets and screws to form a frame. Clamping strips are connected to the bottom surface of the frame beams by screws to fix the covering film to the bottom surface of the frame.

[0010] Furthermore, the crankshaft roller includes a crankshaft, a roller, and a bearing housing. The roller is located on both sides of the frame and is fixed to both ends of the crankshaft by bearings. The crankshaft is laterally fixed to the front and rear positions of the top of the frame by the bearing housing.

[0011] There is a pin hole on the crankshaft directly above the frame beam. The angle between the direction of the pin hole and the bent section of the crankshaft is less than 90 degrees. When a horizontal pin is inserted into the pin hole, the crankshaft is fixed and cannot rotate. At this time, the rollers support the frame, which facilitates the movement of the frame.

[0012] Furthermore, the pin device includes a pin, a compression spring, a guide plate, a fixing plate, a control line, and a handle;

[0013] The guide plate includes a front guide plate and a rear guide plate. The front and rear guide plates and a fixed plate all have guide holes with the center points of the holes on the same straight line. All three are fixed to the top surface of a frame beam on one side. The front guide plate is close to the crankshaft, and the fixed plate is located behind the rear guide plate.

[0014] Furthermore, the pin consists of a front section with a larger cross-section and a rear section with a smaller cross-section. The front section is located on the side closer to the crankshaft and is suitable for insertion into the pin hole of the crankshaft. Its length is greater than the distance from the front guide plate to the bottom of the pin hole. A compression spring is sleeved on the pin with a smaller cross-section, with one end pressing against the pin at the change of cross-section and the other end pressing against the rear guide plate, so that the pin is always pushed toward the pin hole of the crankshaft.

[0015] Furthermore, the control line consists of a wire core and a wire sleeve. One end of the wire core passes through the center hole of the fixing plate and connects to the tail end of the pin, while the other end connects to the handle. One end of the wire sleeve is clipped to the outside of the fixing plate, and the other end is clipped to the handle.

[0016] Before the frame reaches the inlet, the pin is inserted into the pin hole to fix the crankshaft position, so that the rollers support the frame, which can then move back and forth on the ground under the push of the push rod. When the frame reaches directly above the inlet, press the handle and pull the control line backward. The control line pulls the pin backward so that it is disengaged from the pin hole. The crankshaft loses the pin constraint and rotates, and the frame loses the roller support and falls to the ground.

[0017] Furthermore, the push rod includes a Y-shaped rod, several sections of straight rods, and a handle, which are connected to each other by threads;

[0018] One end of the Y-shaped rod is connected to the rear beam of the frame via a pin, and the other end is connected to the straight rod. The handle of the pin device is fixed to both ends of the handle.

[0019] Furthermore, the covering membrane is a waterproof film.

[0020] The beneficial effects of this utility model are: 1. The entire device adopts an assembly structure, which is simple in structure, convenient for transportation of each component, and quick to assemble.

[0021] 2. The entire device is safe and quick to operate. Rescue personnel only need to assemble and operate it on the safety embankment without going into the water, so the safety risk is very small. The time required from assembly to sealing the seepage inlet is short, which can achieve quick sealing and complete the emergency treatment of pipeline piping. Attached Figure Description

[0030] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0031] Suppose a piping failure is occurring on the lower part of a river embankment. The piping pipe has a diameter of 0.5m and a large flow rate, requiring urgent emergency treatment. The treatment method is to seal the inlet from the inside of the embankment. It has been decided to use a ground-mounted mobile piping failure inlet covering device provided by this utility model to cover and seal the inlet.

[0032] like Figures 1-8 As shown, a ground-mobile pipe inflow inlet covering device is an assembled structure, including a frame 1, crankshaft rollers 2, pin devices 3, covering membrane 4, and push rod 5. The frame 1 is square, the covering membrane 4 is fixed to the bottom surface of the frame 1, the crankshaft rollers 2 and pin devices 3 are fixed to the top surface of the frame 1, and the push rod 5 is connected to the frame 1 by pins. The entire device resembles a small cart with a covering membrane.

[0033] Frame 1 consists of four frame beams 101, four brackets 102, and four clamping strips 103. The frame beams 101 are made of square tubing or lightweight steel (such as angle steel, I-beams, or channel steel), with a length approximately three times the diameter of the leakage hole, about 1.5m. This means the length extends by twice the diameter of the leakage hole on each side of the seepage inlet edge. The beams are connected and fixed to each other using brackets 102 with screws, forming a stable square frame with sides of 1.5m. The brackets 102 are right-angled, with sides of approximately 20-30cm, and have metal reinforcing plates between their wings. They are used to connect the frame beams 101 to form frame 1, securing the frame with screws. The clamping strips 103 are strips, 1.5m long, the same length as the frame beams 101, and are connected to the bottom surface of the frame beams 101 with screws, used to fix the covering membrane 4 to the bottom surface of frame 1.

[0034] The crankshaft roller 2 consists of a crankshaft 201, rollers 202, and bearing housings 203. The crankshaft has a circular cross-section and consists of a straight section in the middle and right-angled bends at both ends in the same direction. The straight section is approximately 1.6m long, slightly wider than the width of frame 1. The length of the bends at both ends is 5-10cm longer than the height of frame 1. Rollers 202 are located on both sides of frame 1 and are fixed to the ends of the crankshaft by bearings. The diameter of rollers 202 is approximately 15cm. There are two crankshaft rollers, which are laterally fixed to the front and rear positions of the top of frame 1 by bearing housings 203. There is a pin hole on the crankshaft 201 directly above the frame beam, with its direction forming an angle of approximately 80° with the bends of the crankshaft. When a horizontal pin is inserted into the pin hole, the crankshaft is fixed and cannot rotate. At this time, rollers 202 support frame 1. The distance between the bottom surface of the frame and the ground is approximately 12cm. This distance should generally not be less than 10cm to facilitate frame movement.

[0035] The pin device 3 consists of a pin 301, a compression spring 302, a guide plate 303, a fixing plate 304, a control line 305, and a handle 306. Both the front and rear guide plates 303 and the fixing plate 304 have guide holes with their centers on the same straight line. All three are fixed to the top surface of one side frame beam 101. The front guide plate 301 is close to the crankshaft 201, and the fixing plate 304 is located behind the rear guide plate 303. The pin 301 consists of a front section with a larger cross-section and a rear section with a smaller cross-section. The front section, near the crankshaft 201, can just be inserted into the crankshaft pin hole, and its length is greater than the distance from the front guide plate to the bottom of the pin hole. The compression spring 302 is fitted onto the smaller cross-section pin, with one end pressing against the pin's cross-section and the other end pressing against the rear guide plate 303, constantly pushing the pin 301 towards the crankshaft 201 pin hole. The control line 305 consists of a core and a sleeve. One end of the core passes through the center hole of the fixing plate 304 and connects to the tail end of the pin 301. The other end connects to the handle 306, which is fixed to the push rod handle 503. One end of the sleeve is secured to the outside of the fixing plate 304, and the other end is secured to the handle 306. By pressing the handle 306, the pin 301 can be pulled backward to disengage from the pin hole. Before the frame 1 reaches the inlet, the pin 301 is inserted into the pin hole to fix the position of the crankshaft 201, allowing the roller 202 to support the frame 1. This facilitates the frame 1's back-and-forth movement on the ground under the push rod's thrust. When the frame 1 reaches directly above the inlet, pressing the handle 306 pulls the control line 305 backward. The control line 305 pulls the pin 301 backward to disengage it from the pin hole. The crankshaft 201, no longer constrained by the pin 301, rotates, and the frame 1, no longer supported by the roller 202, falls to the ground.

[0036] The push rod 5 consists of a Y-shaped rod 501, several sections of straight rods 502, and a handle 503, which are connected to each other by threads. One end of the Y-shaped rod 501 is connected to the rear beam of the frame 1 by a pin, and the other end is connected to the straight rod 502. The straight rod 502 is lengthened section by section as needed, and finally connected to the handle 503. The handle 306 of the pin device 3 is fixed to both ends of the handle 503.

[0037] like Figure 7 , Figure 8 As shown, the covering membrane 4 is a waterproof film, such as ordinary tarpaulin or various polyvinyl chloride films, with a certain tensile strength. Its planar shape and size are the same as the frame. It is fixed to the bottom surface of the frame 1 with clips 103. Its cross-section is arc-shaped, which makes it easy for the covering membrane 4 to fit with the periphery of the infiltration port.

[0038] The installation and operation steps of the covering device are as follows:

[0039] (1) Installation of frame and covering film. The four frame beams 101 are fixed into a stable square frame 1 with a side length of 1.5m by screws and brackets 102. The covering film 4 is then fixed to the bottom of the frame 1 by screws and clamps 103.

[0040] (2) Install crankshaft rollers and pin device. The bearing housing 203, together with the crankshaft 201, is fixed to the front and rear ends of the two side frame beams 101. Rollers 202 are installed at both ends of the crankshaft. The pin device 3 is installed on one side frame beam, that is, the guide plate 303 and the fixing plate 304 are fixed on the side beam 101 by screws, and the pin 301 and the compression spring 302 are installed. The front end of the pin is inserted into the crankshaft pin hole, and the rear end is connected to the control line 305. At this time, the roller 202 supports the frame 1, making it a certain distance away from the ground.

[0041] (3) Install the push rod. Connect the two legs of the Y-shaped push rod 501 to the frame 1 with pins, and connect the other end to the straight rod 502. During the process of pushing the frame 1 forward, lengthen the push rod section by section. At the same time, fix the control line 305 to the push rod 5 with a strap. When the frame 1 reaches the predetermined position, connect the handle 503 and fix the handle 306 of the pin device 3 to the handle 503.

[0042] (4) When the frame 1 reaches the inlet, press the handle 306 and pull the pin 301 to disengage it from the crankshaft pin hole. The crankshaft 201 loses its constraint and rotates freely. The roller 202 no longer supports the frame 1. The frame 1 sits on the ground under its own weight. The bottom covering film 4 covers the inlet, preventing water from seeping into the piping channel and preventing further damage and expansion of the channel.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
