Technical Field
[0001] The utility model relates to the technical field of water tightness test, and more specifically, to an electrode type water tightness test device based on a water level sensor. Background Art
[0002] Drainage pipes generally refer to a system composed of pipes and their affiliated facilities for collecting and discharging sewage, wastewater, and rainwater. After the laying of drainage pipes is completed, it is usually necessary to conduct a water tightness test on the drainage pipes to determine whether there are defects in the pipe closure by measuring the water level change in the manhole. The water seepage situation of the drainage pipes can most intuitively reflect the buried or applied state of the pipes. Therefore, the pipe water tightness test is an important content of the completion inspection of drainage pipes, and the pipe water seepage volume is the main evaluation parameter for pipe maintenance and renovation, with very high requirements for the accuracy and precision of the pipe water seepage volume. For the water tightness test of newly built pipes in traditional drainage pipe network projects, the tape measure measurement method, plumb bob measurement method, etc. are usually used. In this method, the water level drop is judged by visually observing the tape measure scale or the change of the plumb bob relative to the horizontal plane, and the leaked water volume is confirmed by supplementing the leaked water volume with a measuring cylinder. The traditional detection method is cumbersome to operate, has low efficiency and requires frequent observation, bringing cumbersome work to on-site operation, data processing and analysis of detection. Most importantly, it cannot accurately feedback detection information. The detection personnel judge the initial water level by the human eye. If the water level drops, water is replenished. This process requires high requirements for the detection personnel. The data during the detection process is not intuitive enough, and the operation process is relatively complex, often unable to judge whether the pipe water seepage volume meets the specified standard value within the specified time.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present utility model.
[0024] Such as Figures 1 to 7As shown in the figure, the utility model provides an electrode type water shutoff test device based on a water level sensor, which includes a measuring bucket 1. A fixed plate 2 is fixedly connected to the front end of the measuring bucket 1. A rotating shaft 3 is fixedly connected to the upper end of the fixed plate 2. A first bevel gear 4 is fixedly sleeved on the surface of the rotating shaft 3. The first bevel gear 4 meshes with a second bevel gear 5. A red anode wire 6 is wound around the surface of the rotating shaft 3. A first touch probe 7 is fixedly connected to the lower end of the red anode wire 6. A water tap 9 is inserted into the lower side of the front end of the measuring bucket 1. A power supply 8 is fixedly sleeved on the surface of the water tap 9. A black cathode wire 10 is fixedly connected to the left side of the power supply 8. A second touch probe 11 is fixedly connected to the lower end of the black cathode wire 10. A chute plate 12 is fixedly connected to the front side of the fixed plate 2. A sliding plate 13 is slidably connected to the upper end of the chute plate 12. A connecting rod 14 is fixedly connected to the front side of the sliding plate 13. The connecting rod 14 is sleeved on the front side of the sliding plate 13. A limiting plate 15 is fixedly connected to the front end of the sliding plate 13.
[0025] A semi-open new type of water shutoff test device composed of a power supply 8, a rotating shaft 3, and a measuring bucket 1 is set. A water tap 9 is configured at the bottom of the measuring bucket 1 of the device, and the change of the water level scale can be observed in real time. The device is configured with a water level sensor, including anode and cathode wires, namely a red anode wire 6 and a black cathode wire 10. The red anode wire 6 is lowered to the water surface of the well to be detected, and the first touch probe 7 can be close to the water surface. The black cathode wire 10 can be placed in the water of the measuring cylinder. By observing the change of the scale on the outer wall of the measuring bucket 1 in real time, the water level information can be accurately read.
[0026] Wherein, both ends of the connecting rod 14 are respectively sleeved on the front side of the second bevel gear 5 and the sliding plate 13.
[0027] Through the connection of the connecting rod 14, when the second bevel gear 5 is driven by the first bevel gear 4 to rotate, it pushes the sliding plate 13, and then the red anode wire 6 is limited and sorted by the limiting plate 15 on the front side of the sliding plate 13. This is beneficial to reducing the damage of the device caused by the winding and knotting of the red anode wire 6 during the use and storage of the red anode wire 6.
[0028] Wherein, a chute is opened at the upper end of the chute plate 12 to fit the shape and size of the lower end of the sliding plate 13, and the length value of the chute plate 12 is greater than the length value of the part of the rotating shaft 3 around which the red anode wire 6 is wound.
[0029] The limiting chute structure can provide reliable position control, enabling the sliding plate 13 to accurately reach the target position during movement. The limiting chute structure has good wear resistance and can remain undamaged for a long time.
[0030] Wherein, a limiting hole is opened at the front end of the limiting plate 15, and the diameter value of the limiting hole is greater than the diameter value of the red anode wire 6. The drooping part of the red anode wire 6 passes through the limiting hole.
[0031] When the red anode wire 6 is stored, it can effectively prevent the red anode wire 6 from being wound around the surface of the rotating shaft 3 in sequence with the left and right displacement of the sliding plate 13, reducing the occurrence of knotting, winding and other situations.
[0032] Among them, a scale line is provided on the left side of the measuring barrel 1, and the length value of the black cathode wire 10 is greater than twice the height value of the measuring barrel 1.
[0033] It is convenient to observe the amount of water flow, can more effectively and quickly judge the water consumption, and ensure that the touch probe two 11 can have a sufficient adjustable range and can be placed inside the measuring barrel 1.
[0034] Among them, the sum of the diameter value of the bevel gear two 5 and the length value of the connecting rod 14 is less than the length value of the rotating shaft 3 on the right side of the bevel gear one 4.
[0035] It is ensured that when the connection point of the bevel gear two 5 and the connecting rod 14 is at the rightmost position, the sliding plate 13 will not be pushed out of the range, effectively protecting the winding range of the red anode wire 6.
[0036] Among them, the circumference of the bevel gear two 5 is close to twice the length value of the rotating shaft 3 for winding the red anode wire 6.
[0037] It is ensured that during the rotation of the bevel gear two 5, the process distance of pushing and pulling the connecting rod 14 to cause the sliding plate 13 to move back and forth is within the limited range and will not exceed the range. When the connection point of the bevel gear two 5 and the connecting rod 14 is in the lower half circle, the sliding plate 13 is pushed to the right, and when the connection point of the bevel gear two 5 and the connecting rod 14 is in the upper half circle, it is pulled back to the left.
[0038] Among them, the distance value of the part of the rotating shaft 3 for winding the red anode wire 6 close to the power supply 8 is greater than the power supply 8.
[0039] It can effectively ensure that during the process of putting the touch probe one 7 into the water surface, the touch probe one 7 will not collide with the device itself, reducing the possible collision that the touch probe one 7 may receive.
[0040] The working principle and usage process of the present utility model:
[0041] When a closed water test is required, the device is placed horizontally at the observation port. A faucet 9 is arranged at the bottom of the measuring barrel 1 of the device. The faucet 9 is aligned with the inside of the pipe. The device is equipped with a water level sensor, which includes a red anode wire 6 and a black cathode wire 10 of a positive and negative two-level electric wire. After installation, the rotating shaft 3 is rotated. Then, when the rotating shaft 3 rotates, the bevel gear 1 4 drives the bevel gear 2 5 to push the connecting rod 14 so that the sliding plate 13 makes a left and right reciprocating motion at the upper end of the slide plate 12. Because the red anode wire 6 passes through the limiting hole provided in the limiting plate 15, the red anode wire 6 can be evenly wound on the surface of the rotating shaft 3, avoiding the possible irregular storage of the red anode wire 6, resulting in a dead knot and damage to the device. The rotating shaft 3 rotates the red anode wire 6 and lowers it to the water surface of the well to be tested. The touch probe 1 7 can be close to the horizontal plane, and the black cathode wire 10 can be placed in the water of the measuring barrel. By real-time observation of the scale changes on the outer wall of the measuring barrel 1, the water level information can be accurately read. If the water seepage is serious and the liquid level drops, the touch probe 7 will send a signal and the faucet 9 will drain the water inside the measuring barrel 1 until the liquid level touches the touch probe 7 again. During this process, the worker only needs to observe the changes in the water volume in the barrel to know the result of the water-tightness test. After the test is completed, the rotating shaft 3 is rotated to retract the touch probe 7, and the red anode wire 6 is wound around the surface of the rotating shaft 3.
