Description

Technical Field

[0001] This utility model belongs to the field of municipal engineering technology, specifically relating to a prefabricated water meter well with adjustable height. Background Technology

[0002] A water meter well is an underground structure where water meters and related facilities are installed. It is typically located at the entrance of a building or water supply network and is used to install, protect, and maintain water meters, valves, and other accessories. The main function of a water meter well is to provide a closed, safe, and easily accessible space for operation and maintenance, ensuring the normal operation of the water meter while protecting it from external environmental influences such as temperature changes, rainwater intrusion, or physical damage. It is usually made of materials such as concrete, brick, or plastic, providing strong waterproofing and durability. Its design not only ensures the safety of the water meter but also considers the convenience of meter reading, maintenance, and replacement. The well often includes dedicated inspection holes, drainage holes, and cleaning channels to facilitate regular meter inspection, debris removal, and drainage of accumulated water.

[0003] Chinese patent publication number CN216041326U discloses an adjustable-height prefabricated water meter well, including a base plate and an upper frame. A side bending plate is provided between the base plate and the upper frame, forming a rectangle at the edge between the base plate and the upper frame. Fixing blocks are fixed at the four corners of the upper frame, and adjusting mechanisms that penetrate the corners of the side bending plates are provided on the fixing blocks. An auxiliary heat insulation device is provided inside the side bending plates. The adjustable-height prefabricated water meter well is mainly composed of a base plate, an upper frame, and side bending plates. The side bending plates are composed of multiple sets of bendable reinforced plastic plates. The height of the side bending plates can be adjusted according to the depth of the well pit, thereby adjusting the height of the entire prefabricated water meter well. It is suitable for well pits of different depths, simple to operate, convenient to use, and improves its versatility. Furthermore, the side bending plates can be compressed and shortened during transportation, saving transportation space and facilitating bulk transportation.

[0004] However, the water meter well currently has the following problems: when adjusting the height of the water meter well, staff need to first measure the location where the water meter well is installed, and then adjust the water meter well to the corresponding height, which is time-consuming and labor-intensive. Utility Model Content

[0005] The purpose of this invention is to provide a prefabricated water meter well with adjustable height, which solves the problem that when adjusting the height of a water meter well, workers need to first measure the location where the water meter well will be installed and then adjust the water meter well to the corresponding height, which is time-consuming and labor-intensive.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A prefabricated water meter well with adjustable height includes a fixed shell, a protective frame fixedly connected to the fixed shell, a water meter well cover fixedly connected to the side of the protective frame, a movable shell slidably connected to the inner wall of the fixed shell, an adjustment device provided on the inner wall of the protective frame, the adjustment device including a hexagonal grooved block, the inner wall of the hexagonal grooved block being rotatably connected to the inner wall of the protective frame, a fixed column fixedly connected to the bottom of the hexagonal grooved block, a fixed block fixedly connected to the inner wall of the protective frame, and a movable groove formed on the outer wall of the fixed block. When the fixed shell is placed into the pit to be installed, the top of the fixed shell is fixed in the pit. Above, the worker rotates the hexagonal slotted block using an external tool. The rotation of the hexagonal slotted block causes the torsion spring to deform, which in turn causes the fixed column to rotate. The rotation of the fixed column causes the moving plate to rotate, which in turn causes the push block to rotate. The rotation of the push block causes the vertical rod to move along the arc groove. At this time, the movement of the vertical rod will cause the moving plate to move along the moving groove through the push block. The movement of the moving plate will cause the locking block to move. The movement of the locking block will no longer lock the locking plate. Therefore, the moving shell will move the locking plate downward along the inner wall of the fixed column under its own gravity.

[0008] The adjustment device also includes an arc block fixedly connected to the bottom of the protective frame. The bottom of the arc block has an arc groove. A moving plate is slidably connected to the inner wall of the moving groove. Multiple locking blocks are fixedly connected to the side of the moving plate. A push block is fixedly connected to the side of the moving plate. A vertical rod is fixedly connected to the side of the push block. A locking plate is fixedly connected to the inner wall of the moving shell. When the moving shell moves to the bottom of the pit, the operator no longer rotates the hexagonal groove block. At this time, the torsion spring will drive the hexagonal groove block to reset through its own elastic force. The reset of the hexagonal groove block will drive the fixed column, the moving plate, the push block, and the vertical rod to reset, so that the locking block fixes the locking plate again.

[0009] The outer wall of the vertical rod is slidably connected to the inner wall of the arc groove, and the card plate is located on the displacement trajectory of the card block.

[0010] A torsion spring is provided between the hexagonal slotted round block and the fixed block.

[0011] The bottom of the movable shell is provided with a protective device, which includes two protective rods. The outer walls of the two protective rods penetrate and slide on the bottom of the movable shell. The tops of the two protective rods are fixedly connected to the same support plate. When the movable shell moves to the bottom of the pit, the protective rods will first contact the bottom of the pit.

[0012] A spring is provided between the support plate and the movable shell.

[0013] The technical effects achieved by this utility model are as follows:

[0014] This invention, through the setting of an adjustment device, enables the hexagonal slot block, fixed column, fixed block, torsion spring, moving groove, arc block, arc groove, moving plate, locking block, push block, vertical rod, and locking plate to work together. The torsion spring will drive the hexagonal slot block to reset through its own elasticity. The reset of the hexagonal slot block will drive the fixed column, moving plate, push block, and vertical rod to reset, thereby causing the locking block to fix the locking plate again. This allows the moving shell to be quickly adjusted to the required height, thereby improving work efficiency.

[0015] This utility model, through the setting of a protective device, ensures that the protective rod, spring, and movable shell work together. The protective rod will first contact the bottom of the pit, and under the elastic force of the spring, the movable shell will be buffered, thereby preventing the movable shell from making direct hard contact with the bottom of the pit and preventing excessive impact force that could damage the movable shell.

[0023] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0024] like Figure 1-5As shown, a prefabricated water meter well with adjustable height includes a fixed shell 1, a protective frame 2 fixedly connected to the fixed shell 1, a water meter well cover 3 fixedly connected to the side of the protective frame 2, a movable shell 4 slidably connected to the inner wall of the fixed shell 1, an adjusting device 5 provided on the inner wall of the protective frame 2, the adjusting device 5 including a hexagonal grooved block 51, the inner wall of the hexagonal grooved block 51 being rotatably connected to the inner wall of the protective frame 2, a fixed post 52 fixedly connected to the bottom of the hexagonal grooved block 51, a fixed block 53 fixedly connected to the inner wall of the protective frame 2, a movable groove 55 formed on the outer wall of the fixed block 53, and an arc block 56 fixedly connected to the bottom of the protective frame 2, the bottom of the arc block 56 having an arc groove 57, a movable plate 58 slidably connected to the inner wall of the movable groove 55, and a fixed side of the movable plate 58 being fixedly connected to the inner wall of the movable groove 55. Multiple locking blocks 59 are connected. A push block 510 is fixedly connected to the side of the moving plate 58. A vertical rod 511 is fixedly connected to the side of the push block 510. A locking plate 512 is fixedly connected to the inner wall of the moving shell 4. The outer wall of the vertical rod 511 is slidably connected to the inner wall of the arc groove 57. The locking plate 512 is located on the displacement trajectory of the locking blocks 59. A torsion spring 54 is provided between the hexagonal slot round block 51 and the fixed block 53. According to the above structure, the torsion spring 54 will drive the hexagonal slot round block 51 to reset through its own elasticity. The reset of the hexagonal slot round block 51 will drive the fixed column 52, the moving plate 58, the push block 510, and the vertical rod 511 to reset, so that the locking block 59 fixes the locking plate 512 again. This allows the moving shell 4 to be quickly adjusted to the required height, thereby improving work efficiency.

[0025] In use, the fixing shell 1 is placed into the pit where it needs to be installed. The top of the fixing shell 1 will be fixed to the top of the pit. Then, the operator rotates the hexagonal slotted block 51 using an external tool. The rotation of the hexagonal slotted block 51 will cause the torsion spring 54 to deform. The rotation of the hexagonal slotted block 51 will drive the fixing column 52 to rotate. The rotation of the fixing column 52 will drive the moving plate 58 to rotate. The rotation of the moving plate 58 will drive the push block 510 to rotate. The rotation of the push block 510 will drive the vertical rod 511 to move along the arc groove 57. At this time, the movement of the vertical rod 511 will drive the moving plate 58 to move along the moving groove 55 through the push block 510. The movement of the moving plate 58 will... Moving the locking block 59 will cause it to stop locking the plate 512. Therefore, the moving shell 4 will move the plate 512 downward along the inner wall of the fixed column 52 under its own gravity. When the moving shell 4 reaches the bottom of the pit, the operator will stop rotating the hexagonal slot block 51. At this time, the torsion spring 54 will drive the hexagonal slot block 51 to reset through its own elasticity. The reset of the hexagonal slot block 51 will drive the fixed column 52, the moving plate 58, the push block 510, and the vertical rod 511 to reset, so that the locking block 59 can fix the plate 512 again. This allows the moving shell 4 to be quickly adjusted to the required height, thereby improving work efficiency.

[0026] like Figure 1-5 As shown, a protective device 6 is provided at the bottom of the movable shell 4. The protective device 6 includes two protective rods 62. The outer walls of the two protective rods 62 penetrate and slide on the bottom of the movable shell 4. The top of the two protective rods 62 is fixedly connected to the same support plate 61. A spring 63 is provided between the support plate 61 and the movable shell 4. According to the above structure, the protective rods 62 will first contact the bottom of the pit. Under the elastic force of the spring 63, the movable shell 4 will be buffered, thereby preventing the movable shell 4 from making direct hard contact with the bottom of the pit and preventing excessive impact force that could damage the movable shell 4.

[0027] When in use, when the movable shell 4 moves to the bottom of the pit, the protective rod 62 will first contact the bottom of the pit. Under the elastic force of the spring 63, the movable shell 4 will be buffered, thus preventing the movable shell 4 from making direct hard contact with the bottom of the pit and preventing excessive impact force that could damage the movable shell 4.

[0028] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
