Description

Water quality monitoring box

Technical Field

The utility model belongs to the field of water quality monitoring devices, and particularly relates to a water quality monitoring box.

Background

In the river heavy metal pollutant content fixed point monitoring test, the pH value, dissolved Oxygen (DO), heavy metal ion content and the like of water at the position of the river need to be monitored.

The water quality monitoring box is a container for carrying out fixed-point monitoring test on the content of heavy metal pollutants in rivers, and the corresponding sensors for the water quality data are fixed on the outer side wall of the water quality monitoring box. The monitoring units of the sensors are contacted with water in the water quality monitoring box through holes on the side wall of the water quality monitoring box. The sensor is connected with the computer, so that the computer can acquire corresponding water quality data of the water in the water quality monitoring box.

In general, after the water quality monitoring box has monitored water quality data, water needs to be discharged out of the water quality monitoring box, and then clear water is used for cleaning the inside of the water quality monitoring box frequently. The common means is to connect the clean water through a water gun.

The operation steps are as follows: and (3) detaching a box cover of the water quality monitoring box, and flushing the inside of the water quality monitoring box by using a water gun. The water quality monitoring box has the advantages that as the upper end of the water quality monitoring box is open, water in the process of flushing by a water gun is easy to splash out of the water quality monitoring box and sometimes splashed onto a tester, and the cleaning process is inconvenient, which is a disadvantage; in addition, there is the residue on the water quality monitoring case inner wall, and direct water gun washes, although also can wash the residue, but the water gun washes and can only wash single residue glues gluey position point once, if the residue glues that the point is many, every point all carries out the water gun and washes, will very consume water, waste resource, and this is shortcoming two.

Because the bottom connecting piece, the transmission rod and the upper connecting piece rotate synchronously, the first clamping block and the second clamping block which depend on cuboid shapes can meet the requirement of synchronous rotation, but the connection firmness among the bottom connecting piece, the transmission rod and the upper connecting piece is not high. The first bolt and the second bolt are adopted to further tightly connect the bottom connecting piece, the transmission rod and the upper connecting piece into a whole, so that the influence of factors such as water resistance and the like on the firmness of the bottom connecting piece, the transmission rod and the upper connecting piece in the rotation process is avoided.

Further, a through hole is formed in the bottom wall of the box body, and the bottom connecting piece is arranged in the through hole in a penetrating mode; the perforated surface wall is provided with a first bearing, and the outer ring of the first bearing is fixedly connected with the perforated surface wall; the bottom connecting piece is fixedly connected with the inner ring of the first bearing; the bottom connecting piece is sleeved with a first sealing ring used for sealing the perforation, the first sealing ring is located above the first bearing, the perforated surface wall is provided with a ring groove, and the first sealing ring is located in the ring groove.

The first sealing ring seals the perforation, so that water cannot leak from the perforation. The first bearing is arranged below the first sealing ring so as to avoid water in the box body from contacting the first bearing, thereby avoiding the influence of the water in the box body on the first bearing.

The beneficial effects are that:

1. The first cleaning assembly and the second cleaning assembly are arranged, when in operation, the box cover is covered on the box body, and the third clamping block carries the limiting piece and rotates relative to the box cover through the second bearing. Because the box cover is an opening which is closed above the box body, only the water drain is used as a water outlet, water in the box body can not splash everywhere, and the situation that the water splashes on the body of a tester can not occur.

2. The limiting piece is arranged, and can vertically move relative to the third clamping block, so that the box cover, the second bearing and the limiting piece are only required to move upwards as a whole, the box cover can be prevented from shielding an opening, the cleaning condition in the box body can be observed, whether the cleaning is continued or not is determined, and water is saved.

Since the restriction member 30 is inserted into the third clamping block 23 by means of the insertion hole 31 (both rectangular insertion holes restrict the restriction member 30), the restriction member 30 also rotates synchronously with the transmission rod 11.

S7: the vertical pipes 21 rotate to drive the connecting plates 22 and the bristles on the connecting plates 22 to rotate, so that residues on the inner side wall of the box body 1 are loosened;

S8: because the second hose connector 32 is connected with the first hose connector 24 by means of the third bearing 34, the transmission rod 11 rotates around the axis of the transmission rod 11, but the second hose connector 32 does not rotate around the axis of the transmission rod 11, the second connecting pipe 32 is motionless, the water pump pumps clear water into the box body 1 again, the clear water is sprayed out from the water outlet 37, the side wall of the box body 1 is cleaned by the clear water, the inner side wall and the bottom wall of the box body 1 are brushed by brush hairs, and the water pump pumps water into the box body to flush the inner side wall and the bottom wall of the box body 1; after the water pump is operated for a period of time (for example, 2 minutes), the whole of the cover 27, the second bearing 29 and the limiting member 30 can be lifted upwards, the cleaning condition is observed, and if the cleaning condition is not implemented, the whole of the cover 27, the second bearing 29 and the limiting member 30 is reinserted onto the third clamping block (S4), and S4-S8 are repeated; otherwise, the cleaning is completed.

With the above-described preferred embodiments according to the present utility model as an illustration, the above-described descriptions can be used by persons skilled in the relevant art to make various changes and modifications without departing from the scope of the technical idea of the present utility model.
