Description

Technical Field

[0001] The invention belongs to the technical field of mud measuring equipment, and in particular relates to a drainage pipe mud measuring equipment based on municipal engineering construction. Background Art

[0002] During the construction of municipal engineering projects, silt often accumulates at the bottom of the drainage pipes. Measuring the thickness of the silt with a silt measuring device helps to formulate an appropriate silt cleaning strategy. Mud measuring refers to measuring the thickness of the silt. The silt measuring device is mainly composed of a body, a probe and a mounting frame. The probe is connected to the body through a cable. When in use, the probe is installed at the lower end of the mounting frame, and the mounting frame is fixed at the mouth of the drainage pipe so that the probe is placed below the liquid surface. The probe transmits and receives ultrasonic signals. The ultrasonic wave is reflected back after encountering the interface between water and silt. The installation distance from the probe to the bottom of the pipe minus the distance from the probe to the interface is used to obtain the thickness of the silt at the bottom of the pipe.

[0003] During the use of existing drainage pipe mud measuring equipment based on municipal engineering construction, the size and position of the mounting frame are usually fixed, making it difficult to adjust the height of the probe. When the liquid level changes, it is easy for the probe to not be below the liquid surface, affecting the measurement of the sludge thickness. The applicability is insufficient. In addition, the position of the probe fixed in the drainage pipe by the mounting frame is generally fixed, while the sludge thickness at different positions in the drainage pipe may be different, making it difficult for the probe to measure the sludge thickness at positions other than below the probe. The measurement applicability is insufficient. Summary of the invention

[0004] The purpose of the present invention is to provide a drainage pipe mud measuring device based on municipal engineering construction, which can adjust the height position of a probe in a telescopic mechanism as the liquid level in the drainage pipe rises and falls through a lifting mechanism to keep the probe below the liquid level, thereby reducing the situation where the probe is not below the liquid level and affects the measurement of the sludge thickness.

[0040] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention.

[0041] Example 1

[0042] like Figures 1 to 14 As shown, it is the first embodiment of the present invention, which provides a drainage pipe mud measuring device based on municipal engineering construction, including a shell 10; a telescopic mechanism 20, the telescopic mechanism 20 is arranged at the lower end of the shell 10, the telescopic mechanism 20 includes a winch 21 rotatably connected to the inner wall of the shell 10, a connecting rope 22 is wound around the winch 21, the lower end of the connecting rope 22 is fixedly connected to a probe 23, a telescopic cylinder 24 is arranged on the outer side of the connecting rope 22, the upper end of the telescopic cylinder 24 is fixedly connected to the bottom of the shell 10, the lower end of the telescopic cylinder 24 is fixedly connected to the probe 23, and the interior of the telescopic cylinder 24 is connected to the interior of the shell 10; a lifting mechanism 30, the lifting mechanism 30 is arranged On the outside of the telescopic mechanism 20, it is used to adjust the height position of the probe 23. The lifting mechanism 30 includes a lifting rod 31 slidably connected to the shell 10 in the vertical direction, and a floating block 32 is fixedly installed at the lower end of the lifting rod 31. The interior of the shell 10 is provided with a worm 33 and a worm wheel 34 that mesh with each other. The upper end of the lifting rod 31 is transmission-connected to the worm 33, and the worm wheel 34 is fixedly connected to the capstan 21; a connecting mechanism 40, the connecting mechanism 40 is arranged on the outside of the shell 10, and is used to adjust the position of the probe 23 in the horizontal direction. The connecting mechanism 40 includes a sliding frame 41 slidably installed on the shell 10, and a fixed frame 42 is rotatably installed at one end of the sliding frame 41 away from the shell 10.

[0043] It should be noted that the worm 33 and the worm wheel 34 are self-locking, and the worm 33 can only be used as the active part to drive the worm wheel 34 for transmission, but the worm wheel 34 cannot drive the worm 33 to move. This is an existing mature technology and will not be repeated here. The outer side of the shell 10 is fixedly connected to the body, and the probe 23 is connected to the body through a cable. The body is an existing mature technology. A signal processing circuit, a display, an output interface, and a power supply module are arranged inside the body to process the signal of the probe 23. It will not be repeated here. The fixing frame 42 is fixedly connected to the pipe mouth of the drainage pipe.

[0044] When the present invention is in use, when the liquid level in the drainage pipe rises, the float 32 drives the lifting rod 31 to move upward under the action of buoyancy, and the upper end of the lifting rod 31 drives the winch 21 to rotate through the worm 33 and the worm gear 34, so that the winch 21 reels in the connecting rope 22, and the connecting rope 22 drives the probe 23 to move upward, so that the probe 23 rises with the rising liquid level. When the liquid level in the drainage pipe drops, the float 32 moves downward with the dropping liquid level, and the upper end of the lifting rod 31 drives the winch 21 to rotate through the worm 33 and the worm gear 34, so that the winch 21 releases the connecting rope 22, and the probe 23 moves downward together with the connecting rope 22 under the action of its own gravity, so that the probe 23 drops with the dropping of the liquid level, thereby facilitating the probe 23 to be moved downward. The head 23 is kept below the liquid surface, reducing the situation where the probe 23 is not below the liquid surface and affects the measurement of the sludge thickness, adapting to different liquid level heights, and improving the applicability of the measurement. After the sliding frame 41 rotates along the fixed frame 42, the sliding frame 41 drives the shell 10 and the probe 23 to rotate, so that the probe 23 rotates along the drainage pipe. After the shell 10 slides along the sliding frame 41, the shell 10 drives the probe 23 to move along the sliding frame 41, so that the probe 23 moves along the drainage pipe, thereby adjusting the position of the probe 23 on the horizontal plane of the drainage pipe, avoiding the situation where the probe 23 is difficult to measure the sludge thickness at a position other than below the probe 23, facilitating the measurement of sludge at different positions of the drainage pipe along the horizontal plane, and improving the applicability of the measurement.

[0045] Among them, when the silt at the bottom of the drainage pipe continues to accumulate and the thickness increases, if the probe 23 is set at a fixed height in the traditional way, it is easy to cause the silt to overflow the probe 23 and cause the probe 23 to be inserted into the silt, affecting the sludge measurement. When the present invention is used, the silt thickness at the bottom of the drainage pipe increases and the liquid level rises. The probe 23 rises with the liquid level, so that the probe 23 remains below the liquid surface while being away from the interface between water and silt. Compared with the traditional method, the situation where the probe 23 is inserted into the silt is reduced.

[0046] Example 2

[0047] Reference Figures 1 to 14 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0048] like Figure 4 , Figure 5 and Fig.11 As shown, the upper end of the lifting rod 31 is threadedly connected to a gear barrel 35, which is rotatably mounted on the inner wall of the housing 10, and the worm 33 is rotatably connected to the inner wall of the housing 10. The worm 33 is fixedly connected to a first gear 331, which meshes with the gear barrel 35.

[0049] According to the above structure, when the liquid level in the drainage pipe rises, the float 32 drives the lifting rod 31 to move upward, and the lifting rod 31 drives the gear cylinder 35 to rotate in one direction along the inner wall of the shell 10, and the gear cylinder 35 drives the worm 33 to rotate through the first gear 331, and the worm 33 drives the capstan 21 to rotate through the worm gear 34, so that the capstan 21 reels the connecting rope 22. When the liquid level in the drainage pipe drops, the float 32 drives the lifting rod 31 to move downward, and the lifting rod 31 drives the gear cylinder 35 to rotate in another direction along the inner wall of the shell 10, and the gear cylinder 35 drives the worm 33 to rotate through the first gear 331, and the worm 33 drives the capstan 21 to rotate through the worm gear 34, so that the capstan 21 releases the connecting rope 22, thereby driving the capstan 21 to reel in or release the connecting rope 22 through the rise or fall of the float 32, so that the lifting mechanism 30 adjusts the height position of the probe 23 in the telescopic mechanism 20 as the liquid level in the drainage pipe rises and falls, so that the probe 23 remains below the liquid level.

[0050] like Figure 5 and Fig.11 As shown, the gear cylinder 35 includes a rotating cylinder 351 and a second gear 352. The rotating cylinder 351 is arranged on the outer side of the lifting rod 31. The rotating cylinder 351 is threadedly connected to the upper end of the lifting rod 31. The lower end of the rotating cylinder 351 is integrally connected with a flange 3511. A fixing ring 353 is arranged on the outer side of the flange 3511. The flange 3511 and the fixing ring 353 are rotatably matched. The fixing ring 353 is fixedly connected to the inner wall of the shell 10. A limiting ring 354 is arranged above the flange 3511. The limiting ring 354 is fixedly connected to the fixing ring 353. The second gear 352 is fixedly connected to the outer wall of the rotating cylinder 351. The second gear 352 is meshed with the first gear 331.

[0051] It should be noted that the interior of the rotating cylinder 351 is provided with an internal thread, the outer side of the lifting rod 31 is provided with an external thread, the internal thread and the external thread are threadedly matched, and the inner diameter of the limit ring 354 is smaller than the outer diameter of the flange 3511.

[0052] According to the above structure, when the lifting rod 31 moves up and down along the shell 10, since the gear cylinder 35 can only rotate along the shell 10 but cannot move up and down along the shell 10, the lifting rod 31 drives the gear cylinder 35 to rotate, which is convenient for the gear cylinder 35 to drive the first gear 331 to rotate. In this process, the lifting rod 31 drives the rotating cylinder 351 to rotate after being lifted, and the rotating cylinder 351 drives the second gear 352 and the flange 3511 to rotate. After the second gear 352 rotates, it drives the first gear 331 to rotate, which is convenient for driving the worm 33 to rotate. After the flange 3511 rotates, it rotates along the fixing ring 353. The limit ring 354 prevents the flange 3511 from moving upward to avoid the flange 3511 from being separated from the fixing ring 353, which is convenient for the rotating cylinder 351 to rotate along the shell 10.

[0053] like Figure 1 , Figure 4 , Figure 5 , Fig. 9 , Fig.10 , Fig.12 and Fig.13 As shown, the telescopic cylinder 24 includes an upper cylinder 241 fixedly connected to the bottom of the shell 10, and a lower cylinder 242 is fixedly connected to the top of the probe 23. A plurality of sliding cylinder assemblies 243 are detachably connected between the upper cylinder 241 and the lower cylinder 242 along the vertical direction, and the plurality of sliding cylinder assemblies 243 are slidably installed together.

[0054] According to the above structure, when the winch 21 rotates to release the connecting rope 22, the lower cylinder 242 moves downward together with the probe 23 under the action of its own gravity, avoiding the situation where the probe 23 is difficult to move downward only by its own gravity, and facilitating the downward movement of the probe 23. In the process of the winch 21 winding up or releasing the connecting rope 22, the connecting rope 22 drives the probe 23 and the lower cylinder 242 to rise or fall, so that the distance between the lower cylinder 242 and the upper cylinder 241 is reduced or increased, and the sliding cylinder assemblies 243 slide against each other, so that the overall length of the telescopic cylinder 24 is reduced or increased to adapt to the rise or fall of the probe 23.

[0055] like Figure 1 , Figure 4 , Figure 5 , Fig. 9 , Fig.10 , Fig.12 and Fig.13 As shown, the sliding cylinder assembly 243 includes a first cylinder 244 and a second cylinder 245, the end of the first cylinder 244 is slidably matched with the inner wall of the second cylinder 245 in the vertical direction, the first cylinder 244 and the outer part of the upper cylinder 241 are slidably connected with a plurality of connecting rings 246 in the vertical direction, and the interior of the connecting ring 246 is provided with a limiting groove 2461, the ends of the second cylinder 245 and the lower cylinder 242 are fixedly connected with a limiting column 2451, the limiting column 2451 is slidably matched with the limiting groove 2461, the first cylinder 244 is slidably connected with the adjacent second cylinder 245 through the connecting ring 246, the upper cylinder 241 and the second cylinder 245 are detachably connected through the connecting ring 246, and the lower cylinder 242 and the first cylinder 244 are detachably connected through the connecting ring 246.

[0056] It should be noted that an insertion port is provided at the end of the limiting groove 2461, and the end size of the limiting column 2451 is larger than the width size of the limiting groove 2461, which is used to enable the limiting column 2451 to limit the connecting ring 246, and the end size of the limiting column 2451 is smaller than the aperture size of the insertion port, which is used to enable the limiting column 2451 to be inserted into the interior of the connecting ring 246.

[0057] According to the above structure, when it is necessary to adjust the maximum length of the telescopic cylinder 24 as a whole, the connecting rope 22 and the cable connected to the probe 23 are removed from the probe 23, the lower cylinder 242 is disassembled from the adjacent first cylinder 244, and the number of sliding cylinder assemblies 243 is increased by installing a new sliding cylinder assembly 243 to increase the maximum length of the telescopic cylinder 24 as a whole, and the number of sliding cylinder assemblies 243 is reduced by disassembling the existing sliding cylinder assembly 243 to reduce the maximum length of the telescopic cylinder 24 as a whole. When it is necessary to install the upper cylinder 241, the lower cylinder 242, the first cylinder 244 and the second cylinder 245 together, the limiting column 2451 is inserted into the limiting groove 2461 through one end of the limiting groove 2461, and the connecting ring 246 is rotated to move the limiting column 2451 to the limiting groove 2461. At the other end, the limiting column 2451 and the connecting ring 246 are limited, so that the upper cylinder 241 and the second cylinder 245 are installed together, the lower cylinder 242 and the first cylinder 244 are installed together, and the first cylinder 244 and the second cylinder 245 are installed together. At this time, the first cylinder 244 slides relatively along the second cylinder 245 to adjust the overall length of the sliding cylinder assembly 243, and then adjust the overall length of the telescopic cylinder 24. When it is necessary to disassemble the upper cylinder 241, the lower cylinder 242, the first cylinder 244 and the second cylinder 245, the limiting column 2451 is slid along the limiting groove 2461 and then pulled out, so that the limiting of the limiting column 2451 and the connecting ring 246 is released, so that the upper cylinder 241, the lower cylinder 242, the first cylinder 244 and the second cylinder 245 are disassembled.

[0058] like Figure 2 , Figure 5 and Figure 6 As shown, a connecting tube 36 is provided on the outer side of the lifting rod 31, and the connecting tube 36 is fixedly connected to the bottom of the shell 10. A sliding groove 361 is opened on the inner wall of the connecting tube 36, and a slider 311 is fixedly connected to the outer side of the lifting rod 31, and the slider 311 and the sliding groove 361 slide in cooperation along the vertical direction.

[0059] According to the above structure, when the lifting rod 31 moves up and down along the connecting tube 36, the slider 311 cooperates with the slide groove 361 to reduce the rotation of the lifting rod 31, making the process of the lifting rod 31 moving up and down more stable, which is convenient for the lifting rod 31 to drive the gear tube 35 to rotate when it moves up and down.

[0060] like Figure 1 , Figure 3 , Figure 4 , Figure 7 and Figure 8As shown, the lower end of the lifting rod 31 is slidably connected to the connecting rod 37 in the vertical direction, the lower end of the connecting rod 37 is fixedly connected to the floating block 32, and a plurality of first limiting holes 371 are opened inside the connecting rod 37 in the vertical direction. A second limiting hole 312 is opened on the inner wall of the lifting rod 31, and a limiting bolt 38 is connected between the second limiting hole 312 and the first limiting hole 371.

[0061] It should be noted that, in the initial state, the height position of the float 32 is higher than the height position of the probe 23 .

[0062] According to the above structure, when it is necessary to adjust the distance between the float 32 and the probe 23, the limit bolt 38 is removed from the second limit hole 312 and the first limit hole 371, so that the limit bolt 38 on the lifting rod 31 and the connecting rod 37 is released, and the connecting rod 37 is moved up and down along the lifting rod 31, so that the second limit hole 312 is aligned with the first limit hole 371 at a suitable position, and the limit bolt 38 is inserted and connected to the second limit hole 312 and the first limit hole 371 to limit the lifting rod 31 and the connecting rod 37. When the connecting rod 37 moves up and down, it drives the float 32 to move up and down, thereby adjusting the height position of the float 32, and then facilitating the adjustment of the distance between the float 32 and the probe 23 in the initial state, so that in the initial state, when the float 32 floats in the drainage pipe, the probe 23 is located below the liquid surface of the drainage pipe.

[0063] like Figure 8 As shown, the interior of the floating block 32 is designed as a cavity, the outer wall of the floating block 32 is integrally provided with an elastic portion 321 , and the top of the floating block 32 is provided with an air inlet 322 .

[0064] It should be noted that the elastic portion 321 is made of elastic material.

[0065] According to the above structure, when it is necessary to adjust the buoyancy of the float 32, the interior of the float 32 is inflated or deflated through the air inlet 322, so that the elastic part 321 expands outward or contracts inward to adjust the volume of the float 32 and adjust the weight of the fluid displaced by the float 32, thereby adjusting the buoyancy of the float 32, making it easier for the float 32 to drive the lifting rod 31 to move up and down.

[0066] like Fig.14 As shown, a connecting plate 43 is fixedly connected to one side of the housing 10 close to the sliding frame 41 , and the connecting plate 43 is slidably connected to the sliding frame 41 . An electric telescopic rod 44 is fixedly connected to the sliding frame 41 , and an output end of the electric telescopic rod 44 is fixedly connected to the connecting plate 43 .

[0067] It should be noted that the direction in which the output end of the electric telescopic rod 44 is telescopically extended is the same as the direction in which the connecting plate 43 slides along the sliding frame 41 .

[0068] According to the above structure, after the electric telescopic rod 44 works, the output end drives the connecting plate 43 to slide along the sliding frame 41, and the connecting plate 43 drives the probe 23 to slide along the sliding frame 41 through the shell 10, thereby adjusting the position of the probe 23 on the horizontal plane, making it convenient for the probe 23 to measure mud at different positions of the drainage pipe.

[0069] like Fig.14 As shown, a motor 45 is fixedly connected to one end of the fixed frame 42 close to the sliding frame 41 , and an output end of the motor 45 is fixedly connected to the sliding frame 41 .

[0070] According to the above structure, after the motor 45 works, the output end drives the sliding frame 41 to rotate along the fixed frame 42, and the sliding frame 41 drives the probe 23 to rotate along the fixed frame 42 through the shell 10, thereby adjusting the position of the probe 23 on the horizontal plane, making it convenient for the probe 23 to measure mud at different positions of the drainage pipe.

[0071] The working principle of the present invention is as follows: when the liquid level in the drainage pipe drops, the floating block 32 drives the lifting rod 31 to move downward along the shell 10 after the liquid level drops, and the lifting rod 31 drives the capstan 21 to release the connecting rope 22 through the worm 33 and the worm gear 34, so that the probe 23 moves downward along the connecting rope 22 under the action of its own gravity, thereby facilitating the probe 23 to move downward when the liquid level drops, thereby reducing the situation in which the probe 23 is exposed above the liquid surface after the liquid level drops and affects the measurement of the sludge thickness, and the sliding frame 41 rotates along the fixed frame 42 and drives the shell 10 and the probe 23 to rotate, and the shell 10 slides along the sliding frame 41 and drives the probe 23 to move, so as to adjust the position of the probe 23 on the horizontal plane, so as to facilitate the probe 23 to measure the thickness of the sludge at different positions of the drainage pipe along the horizontal plane, thereby improving the applicability of the measurement.

[0072] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
