Description

Technical Field

[0001] This utility model relates to the field of construction dewatering technology, specifically to a construction dewatering structure for hydraulic structures. Background Technology

[0002] Water conservancy projects often involve complex geological conditions and structures located at high groundwater levels. To ensure construction safety and quality, dewatering becomes an essential measure when groundwater levels are high and pumping cannot meet drainage needs. Dewatering is carried out using well dewatering. First, drilling rigs are used to drill holes and lower dewatering well pipes. Filter material is then evenly backfilled around the well walls, allowing groundwater to seep into the well. After the wells are drilled, appropriate pumping equipment is installed.

[0003] Chinese Patent No. CN220318569U discloses a dewatering structure for the construction of a hydraulic structure, including a limiting seat. The limiting seat has a through groove in the middle of its upper end. Support plates are fixedly connected to the left and right parts of the upper end of the limiting seat. A motor is fixedly installed on the upper right end of the support plate on the right side. A rotating rod is fixedly connected to the output end of the motor. The end of the rotating rod away from the motor is movably connected to the support plate on the left side through a bearing.

[0004] Regarding the disclosed technology, the end fixing mechanism of the pumping pipe relies on two sets of pulleys to achieve contact with the well wall. However, the pulleys located on the left and right sides cannot play a limiting role. The end of the pumping pipe will rotate and swing along the axis in the left and right direction, thus losing the clamping and limiting effect. The end of the pumping pipe will still affect pumping due to shaking. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a dewatering structure for hydraulic structures to solve the problem of water pumping being affected by the shaking at the end of the pumping pipe.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a water dewatering structure for construction of a hydraulic structure, comprising a sleeve, wherein a limiting clamp is threadedly installed on the surface of the sleeve, and the clamping end of the limiting clamp is located inside the sleeve, and the limiting clamp is in two sets, arranged symmetrically, a pushing member is provided on the surface of the sleeve, and a fixing ring is slidably installed inside the sleeve, and the fixing ring is connected to the telescopic end of the pushing member.

[0007] The pusher includes a first fixing plate, a scissor bracket, and a second fixing plate. The first fixing plate is fixedly installed on the outside of the sleeve and is connected to one end of the scissor bracket. The second fixing plate is connected to the other end of the scissor bracket. A positioning rod is fixedly installed on one side of the second fixing plate, and the positioning rod has a semi-circular cross-section.

[0008] The sleeve includes a cylinder, a sliding groove, and a limiting groove. The sliding groove is provided on the surface of the cylinder and extends through the inner and outer sides of the cylinder. A limiting groove is provided on the inner surface of the cylinder. Both the sliding groove and the limiting groove are correspondingly arranged with the fixing ring.

[0009] The limiting clamp includes a sleeve plate, a bolt, and a clamping plate. The sleeve plate is threadedly installed on the bottom surface of the sleeve, the bolt is slidably installed on the bottom surface of the sleeve, and one end of the sleeve plate is rotatably connected to one side of the bolt. The clamping plate is fixedly installed on the other side of the bolt, and the other end of the bolt is rotatably connected to one side of the clamping plate.

[0010] The first and second fixing plates have grooves on the side near the scissor bracket. The scissor bracket consists of two sets of rotating rods that are rotatably connected. Fixing blocks are rotatably installed at both ends of the rotating rods. The fixing blocks at both ends of one set of rotating rods are fixedly connected to the first fixing plate and slidably connected to the groove of the second fixing plate, respectively. The fixing blocks at both ends of the other set of rotating rods are fixedly connected to the second fixing plate and slidably connected to the groove of the first fixing plate, respectively.

[0011] The number of pushers and positioning rods is multiple, and the multiple sets of pushers and positioning rods are arranged in a circular array on the outside of the sleeve.

[0012] The fixing ring includes a ring body, a plug and a spring. The ring body is slidably installed inside the sleeve. A connecting plate is fixedly installed at the bottom of the ring body. A plug is slidably installed on the surface of the ring body. A spring is fixedly connected to one side of the plug. The free end of the spring is fixedly connected to the inner side of the ring body.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention pushes the fixed ring to slide inside the sleeve, causing the fixed ring to drive multiple sets of scissor brackets to contract or extend. The extension and retraction of the scissor brackets drive the second fixed plate to move away from or towards the sleeve axis, thereby controlling multiple sets of positioning rods to adhere to the well wall surface. This limits the shaking of the end of the pumping pipe. The semi-circular cross-section of the positioning rod and the well wall have a near-linear contact area, reducing the frictional resistance between the positioning rod and the well wall. This ensures the stable up-and-down movement of the sleeve without hindering its descent, preventing the end of the pumping pipe from shaking. Attached Figure Description

[0020] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0021] Figures 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 -Appendix Figure 4 The present invention will be further described below.

[0022] A dewatering structure for hydraulic structure construction includes a sleeve 1. The top of the sleeve 1 is connected to the rope of a winch. A limiting clamp 2 is threadedly installed on the surface of the sleeve 1, and the clamping end of the limiting clamp 2 is located inside the sleeve 1. There are two sets of limiting clamps 2 arranged symmetrically. A pusher 3 is provided on the surface of the sleeve 1. A fixing ring 5 is slidably installed inside the sleeve 1 and is connected to the telescopic end of the pusher 3. The pusher 3 includes a first fixing plate 301, a scissor bracket 302, and a second fixing plate 303. The first fixing plate 301 is fixedly installed on the outside of the sleeve 1 and is connected to one end of the scissor bracket 302. The second fixing plate 303 is connected to the other end of the scissor bracket 302. A positioning rod 4 is fixedly installed on one side of the second fixing plate 303. The positioning rod 4 has a semi-circular cross-section.

[0023] Specifically, by twisting the limiting clamp 2, the two sets of limiting clamps 2 move towards each other to clamp and fix the end of the pumping pipe. Through the retractable and extendable effect of the scissor bracket 302, the second fixing plate 303 is pushed to move accordingly, thereby controlling the positioning rod 4 on it to fit against the well wall, realizing the stable up and down movement of the sleeve 1 in the well. Through the fixing ring 5, multiple sets of pushing parts 3 are pushed to move synchronously, thereby quickly adjusting the multiple sets of scissor brackets 302 to perform telescopic movements and change the position of the positioning rod 4.

[0024] The sleeve 1 includes a cylinder 101, a sliding groove 102 and a limiting groove 103. The sliding groove 102 is provided on the surface of the cylinder 101 and extends through the inner and outer sides of the cylinder 101. The limiting groove 103 is provided on the inner surface of the cylinder 101. The sliding groove 102 and the limiting groove 103 are both corresponding to the fixing ring 5.

[0025] Specifically, the sliding groove 102 allows the fixing ring 5 to pass through the inner and outer sides of the cylinder 101 and connect with the scissor bracket 302, thereby driving the scissor bracket 302 to perform telescopic movement. The limiting groove 103 allows the fixing ring 5 to be fixed on the inner side of the cylinder 101.

[0026] The limiting clamp 2 includes a sleeve plate 201, a bolt 202, and a clamping plate 203. The sleeve plate 201 is threadedly installed on the bottom surface of the sleeve 1. The bolt 202 is slidably installed on the bottom surface of the sleeve 1, and one end of the sleeve plate 201 is rotatably connected to one side of the bolt 202. The clamping plate 203 is fixedly installed on the other side of the bolt 202, and the other end of the bolt 202 is rotatably connected to one side of the clamping plate 203.

[0027] Specifically, by twisting the sleeve plate 201, it pushes the bolt 202 to slide on the surface of the sleeve 1, thereby causing the clamping plate 203 to move along the axis perpendicular to the sleeve 1.

[0028] The first fixing plate 301 and the second fixing plate 303 are both provided with grooves on the side close to the scissor bracket 302. The scissor bracket 302 is composed of two sets of rotating rods that are rotatably connected. Fixed blocks are rotatably installed at both ends of the rotating rods. The fixed blocks at both ends of one set of rotating rods are fixedly connected to the first fixing plate 301 and slidably connected to the groove of the second fixing plate 303, respectively. The fixed blocks at both ends of the other set of rotating rods are fixedly connected to the second fixing plate 303 and slidably connected to the groove of the first fixing plate 301, respectively.

[0029] Specifically, by pushing two sets of rotating rods to slide within the grooves of the first fixed plate 301 and the scissor bracket 302 respectively, the second fixed plate 303 is moved away from or closer to the first fixed plate 301.

[0030] The number of pushers 3 and positioning rods 4 is multiple, and the multiple sets of pushers 3 and positioning rods 4 are arranged in a circular array on the outside of the sleeve 1;

[0031] Specifically, multiple sets of positioning rods 4 are attached to the surface of the well wall to ensure that the up and down movement of the sleeve 1 is sufficiently stable.

[0032] The fixed ring 5 includes a ring body 501, a plug 502, and a spring 503. The ring body 501 is slidably installed inside the sleeve 1. A connecting plate is fixedly installed at the bottom of the ring body 501, and the connecting plate passes through the slide groove 102 and is connected to the rotating part of the scissor bracket 302 and the rotating part of the fixed block. The plug 502 is slidably installed on the surface of the ring body 501. The plug 502 is slidably inserted into the limiting groove 103. A spring 503 is fixedly connected to one side of the plug 502. The free end of the spring 503 is fixedly connected to the inner side of the ring body 501.

[0033] Specifically, by pushing the ring 501 to slide inside the sleeve 1, the connecting plate drives the rotating rod of the scissor bracket 302 to slide, controlling the scissor bracket 302 to extend and retract. The spring 503 pulls the plug 502 toward the surface of the ring 501, so that the plug 502 is inserted into the limiting groove 103 to limit and fix the ring 501.

[0034] In summary: When using this utility model, the operator connects the sleeve 1 to the rope of the winch, adjusts the sleeve 1 to the wellhead, and pulls the insert 502 out of the limiting groove 103, causing the spring 503 to be stretched and pushing the ring 501 to slide inside the sleeve 1. The connecting plate at the bottom of the ring 501 slides through the sliding groove 102. The connecting plate drives a set of rotating rods of the scissor bracket 302 to slide in the groove of the first fixed plate 301, thereby controlling the rotation of the two sets of rotating rods. This causes the scissor bracket 302 to push the second fixed plate 303 to move away from the first fixed plate 301. The movement of the ring 501 controls the synchronous movement of multiple sets of second fixed plates 303. Move until the positioning rod 4 on the surface of the second fixing plate 303 contacts the surface of the well wall. Release the pull on the plug 502, so that the spring 503 drives the plug 502 to insert it into the limiting groove 103, limiting and fixing the ring 501, and fixing the position of the positioning rod 4. Move the end of the pumping pipe between the two sets of limiting clamps 2. Twist the sleeve plate 201 to make the bolt 202 slide at the bottom of the sleeve 1, control the two sets of clamps 203 to move towards each other, clamp and fix the end of the pumping pipe, drive the winch to lower the sleeve 1 to the bottom of the well, and rely on the positioning rod 4 to stick to the well wall to make the descent process of the sleeve 1 stable and avoid the end of the pumping pipe from shaking.

[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
