DETAILED DESCRIPTION OF EMBODIMENT (S) OF INVENTION
The embodiment provides an automatic weighing water distribution test device consisting of 16 water collection units 10 arranged 4 by 4. The outer edges of the 16 water collecting units 10 are in a straight configuration and all the water collecting units 10 are in a square configuration, so that the two water collecting units 10 can be almost perfectly spliced together when installed. Therefore, the tops of the wedge-shaped knife-shaped opening structures of the water collecting units 10 are almost in seamless butt joint after splicing, and most of splashed water can be reduced. The sliding slope part 13 of the wedge-shaped knife-shaped opening structure is uniformly inclined from the top of the assembling part 12 to the inner side edge of the assembling part 11, and splashed water drops fall to the sliding slope part and flow back to the water collecting box 9 along the slope.
The partition plate 7 in the water tank body 2 is in a cross shape, and the partition plate 7 divides the inside of the water tank body 2 into four equally-divided square water collecting boxes 9. Each of the 16 water collection units 10 has 4 water collection boxes 9, so that 8 by 8 water collection boxes 9 constitute a matrix, and each water collection box 9 corresponds to each data unit in one data matrix. Wherein, the solenoid valve 3 in each water collecting unit 10, the solenoid valve 3 of the weighing inclined water tank 4 and the weighing module 5 are connected with the main control unit 30 through data lines and the like.
The spraying unit 20 adopts a frame 21 erected in the existing water distribution test, a water pipe is erected at the top of the frame 21, a tested object is simulated, and a plurality of suspended ceiling nozzles 22 are installed at corresponding intervals, angles and positions on the water pipe and used for simulating the real spraying state of the tested object. The rear end of the water pipe is connected to a water supply mechanism 23, and the water supply mechanism 23 uses an existing water pump. After the water pump is started, water flows enter the top of the water pipe and sprays water into the water collecting unit 10 below through the ceiling nozzle 22, the water collecting unit 10 collects water in sprayed water mist, different water collecting boxes 9 represent the water spraying conditions of the water mist at different positions, and the water distribution condition of the measured object is evaluated through the water spraying data.
After the water distribution test device is arranged, the concrete operation of the water distribution test can be started.
First, the main control unit 30 turns on the water supply mechanism 23, and the water supply mechanism 23 pumps tap water into the ceiling nozzle 22 through a water pipe. The water mist is formed by spraying through the ceiling nozzle 22, and tap water in the water mist is collected in the whole water collecting unit 10. After the time specified by the test is reached, the main control unit 30 closes the water supply mechanism 23, and at this time, the water collection unit 10 has completed the water quantity collection step in the whole water distribution test.
The main control unit 30 is provided therein with data matrixes corresponding to the respective water collecting boxes 9 in the water collecting unit 10. This embodiment uses 4 × 4 water collecting units 10 in total, i.e. 64 water collecting boxes 9 constitute this 8 × 8 data matrix. For convenience of explanation, the sump case 9 positioned at the upper left in each sump case 9 is defined as a first sump case 9, the sump case 9 positioned at the upper right is defined as a second sump case 9, the sump case 9 positioned at the lower left is defined as a third sump case 9, and the sump case 9 positioned at the lower right is defined as a fourth sump case 9.
After the above definition and initialization of the data matrix are completed, the main control unit 30 opens the solenoid valve 3 on the water outlet 8 at the bottom of the first water collecting box 9 in each water collecting unit 10, the liquid in the first water collecting box 9 flows into the weighing inclined water tank 4 below, and the solenoid valve 3 at the bottom of the weighing inclined water tank 4 is in a closed state. The main control unit 30 starts the weighing module 5, weighs the weight of the liquid in the weighing inclined water tank 4, and records the weight in the unit of the corresponding data matrix by the main control unit 30. After the weighing of the water amount in the first water collecting box 9 is completed, the main control unit 30 opens the electromagnetic valve 3 at the water outlet 8 of the weighing inclined water tank 4 to empty the liquid in the weighing inclined water tank 4, and the main control unit 30 performs the zero setting operation on the weighing module 5. Therefore, the weighing at each time can be more accurate, and the generation of accumulated errors is avoided.
After the first water collecting box 9 in each water collecting unit 10 is weighed, the main control unit 30 sequentially weighs the weights of the liquids in the second water collecting box 9, the third water collecting box 9 and the fourth water collecting box 9 according to the steps until the liquids in all the water collecting boxes 9 in the water collecting units 10 are weighed, and a data matrix for recording all weight data is obtained, namely, the data collection of the water distribution test is completed.
The whole process of the water distribution test is particularly focused on improving the data collection link. The batch weighing operation is performed for four times in the data collection process, so that the time of the data collection link and the consumed manpower are shortened. Wherein the number of batch weighing operations corresponds to the number of the water collecting boxes 9 in each water collecting unit 10. For example, if only two water collection boxes 9 are included in the water collection unit 10, a complete data matrix can be obtained by performing a total of two batch weighing operations.
In conclusion, the invention has the following beneficial effects:
1. compared with a normal common box, the wedge-shaped knife-shaped opening can reduce most of splashed water. The wedge-shaped knife-like opening provides an inclined ramp at the top, so that the splashing water drops fall down the ramp back into the collecting box 9.
2. Because the edge of the wedge-shaped knife-shaped opening is assembled in a detachable mode, the maintenance cost and time can be greatly reduced. Compared with other components, the edge of the wedge-shaped opening on the outer side is inevitably damaged in the moving and assembling processes, and the edge of the wedge-shaped opening of the water collecting unit 10 is detachable, so that when only the edge is damaged, the edge of the wedge-shaped opening can be detached and maintained independently. Thus, such a design may greatly reduce cost and time as compared to repairing or replacing the entire water collection unit 10.
3. The water collecting unit 10 adopts the design of a Frounet wheel and a level gauge, and due to the level gauge, whether the whole water collecting platform is positioned on the horizontal ground or not can be ensured.
4. The whole conveying and weighing process is supervised by the main control unit 30, and the main control unit 30 can control the conveying by controlling the opening and closing of the electromagnetic valve 3 on the conveying port; and the weighing readings of the weighing boxes are synchronously displayed on the main control unit 30, and when the weighing is finished, the driving end can control the drainage by controlling the electromagnetic valve 3 below the weighing boxes.
5. The weighing inclined water tank 4 and the weighing module 5 weigh in sequence, and the weighing method has the advantages that each weighing corresponds to a corresponding spraying test, the accumulative error caused by accumulative weighing is avoided, and the weighing accuracy is greatly improved. The weighing accuracy is significantly higher in sequence than for a level gauge.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, improvements, equivalents and the like that fall within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
