Description

anti-blocking joint of piezoresistive water level meter

Technical Field

The utility model relates to a fluviograph connects, especially a stifled joint is prevented to piezoresistive fluviograph.

Background

The existing piezoresistance water level gauge is mostly installed by a sleeve method, namely, a probe of the water level gauge is put into a pipeline, and then the aim of fixing the probe is achieved through fixing the pipeline. The method is found to be simple and feasible through practical application, but has obvious disadvantages.

1. Because the diameter of the pipeline is close to that of the probe, in a river section with much sediment, the sediment is easy to be clamped between the probe and the pipeline after entering the pipeline, and the longer the time is, the more the sediment is accumulated in the gap, the measurement precision is influenced, and finally the probe is damaged.

2. If the pipeline is big with the big difference of probe diameter size, can effectual solution jam problem to a certain extent, but too big space can increase the live distance of probe, can lead to the probe to rock in the pipeline when rivers torrential, influences the life-span of measurement accuracy and measuring line, probably leads to the measuring line fracture for a long time, and the probe is lost.

Disclosure of Invention

An object of the utility model is to provide a stifled joint is prevented to piezoresistive fluviograph. Should prevent stifled joint and can come most silt in the rivers, avoid silt to pile up the jam, further reduced the risk that the pipeline is blocked up, prolonged the life of probe.

The technical scheme of the utility model: the utility model provides a stifled joint is prevented to piezoresistive water level gauge, is including the sleeve pipe, is provided with a plurality of fixing device that stretch out to the intraduct on the pipe body in the middle part of the sleeve pipe, and fixing device fixes the probe in the intraduct, and the sleeve pipe embolias to preventing stifled intraduct, prevents stifled pipe both ends face interval and is equipped with the fixed bolster and prevents mud grid, prevents stifled pipe through fixed bolster and bushing, is located to prevent that the intraduct sleeve pipe body of stifled intraduct gathers and has plum blossom type trompil.

Aforementioned stifled joint is prevented to piezoresistive fluviograph, prevent that the fixed bolster of stifled pipe both ends respectively is connected with 1 snap ring with preventing the mud grid, during the sleeve pipe stretched into the snap ring, snap ring side was through screw and bushing.

According to the anti-blocking joint of the piezoresistive water level meter, the fixing device is a plurality of fixing screws arranged on the sleeve in an array mode.

The utility model has the advantages that: compared with the prior art, the utility model discloses a be provided with outward at the sleeve pipe and prevent stifled pipe, prevent that stifled pipe terminal surface is provided with and prevent the mud grid, and the while is preventing densely covered plum blossom type trompil on stifled inside sleeve pipe, in the use, prevents mud grid and plum blossom type trompil and can realize 2 times filtering. Prevent that mud grid filters most silt of aquatic, prevent that the probe from being stifled, quincunx trompil can effectually prevent that silt from entering into the sleeve pipe, has further reduced the risk that the pipeline is stifled, has prolonged the life of probe. In addition, the fixing device in the sleeve simply and effectively fixes the probe in the sleeve, thereby avoiding the influence of water flow impact on the probe and improving the measurement precision of the probe. In addition, all the joint materials are common materials in life, the cost is lower, the joint materials are more convenient to install and use in practice, and the requirement on installation personnel is low.

Detailed Description

The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.

The embodiment of the utility model provides a: the utility model provides a piezoresistive water level gauge prevents stifled joint, as shown in the attached figure 1-5, including 1 sleeve pipe 2, be provided with a plurality of fixing device 4 that stretch out to the inside of sleeve pipe 2 on the casing 2 middle part pipe body, fixing device 4 fixes probe 1 inside sleeve pipe 2, sleeve pipe 2 embolias to preventing stifled pipe 3 in, prevents stifled 3 both ends faces intervals of pipe and is equipped with fixed bolster 5 and mud grid 6, is equipped with the round hole that supplies sleeve pipe 2 to penetrate in the middle of the terminal surface. The anti-blocking pipe 3 is connected with the sleeve 2 through a fixed support 5, and plum blossom-shaped openings 7 are densely distributed on the pipe body of the sleeve 2 positioned inside the anti-blocking pipe 3.

During the use, sleeve pipe 2's head end and pipe connection, whole anti-blocking joint places in the aquatic, and rivers flow when this anti-blocking joint, when silt is more in rivers, partly silt is through preventing stifled 3 terminal surfaces of pipe, by the isolation of the mud grid 6 that prevents that sets up on its terminal surface, a small amount of silt enters into along with rivers and prevents stifled 3 insides of pipe, enters into to preventing the in-process of the rivers in the stifled pipe 3 entering into to sleeve pipe 2, and silt in its rivers is by the 7 separation of plum blossom mold trompil on the sleeve pipe 2. After two anti-blocking filtering measures, the sediment entering the water of the sleeve 2 is greatly reduced, the probability of blocking the probe 1 is reduced, and the service life of the probe 1 is prolonged. Meanwhile, the fixing device 4 in the sleeve 2 can effectively fix the probe 1 in the sleeve 2, so that the probe 1 is prevented from swinging along with water flow, and the measurement precision and the service life of a wiring position are improved.

Prevent that the fixed bolster 5 of stifled pipe 3 both ends end respectively is connected with 1 snap ring 8 with preventing mud grid 6, prevents stifled pipe 3, fixed bolster 5, prevents mud grid 6 and snap ring 8 and be the integrated into one piece structure. The sleeve 2 extends into a snap ring 8, and the side surface of the snap ring 8 is connected with the sleeve 2 through a screw 9. The anti-blocking pipe 3 and the sleeve 2 are made of plastics. In the fixing process, the sleeve 2 with the probe 1 fixed is arranged inside the anti-blocking pipe 3, the quincunx-shaped opening 7 formed in the sleeve 2 is ensured to be positioned inside the anti-blocking pipe 3 in the arranging process, and then the snap ring 8 and the sleeve 2 are fixed together by using the screw 9. Thereby the position of the anti-blocking pipe 3 is fixed by 2 snap rings 8.

The fixing means 4 is a plurality of fixing screws arranged in an array on the casing 2. After the head end of the fixing screw is screwed into the sleeve 2, the head end of the fixing screw is abutted against the probe 1, so that the probe 1 is fixed. Set screw's the length that sets up should guarantee that its head end fixes back with probe 1, and its set screw's nut terminal surface just twists into to sleeve pipe 2's pipe wall to guarantee that sleeve pipe 2 can follow snap ring 8 and put into to prevent stifled tub 3, avoid twisting behind the set screw, sleeve pipe 2's thickness increase leads to it can't put into to prevent stifled tub 3 from snap ring 8.
