Description

Technical Field

[0001] The utility model relates to the technical field of water quality detection, in particular to a water quality sampling box. Background Art

[0002] A water sampling box is a box specially used to place water samples. It is usually used to place water samples when sampling water quality. Most of the current water sampling boxes can only place water samples. When using them, you need to manually pour the water samples into the sample bottles and then put them into the sampling box for storage. The water sampling and placement operations of several sample bottles need to be repeated. This process is very slow and the sampling and boxing efficiency is low.

[0003] Therefore, in view of the shortcomings of the above-mentioned scheme in actual production and implementation, it has been revised and improved. At the same time, in the spirit and concept of seeking excellence, with the assistance of professional knowledge and experience, and after much ingenuity and experimentation, a water quality sampling box is provided to solve the technical problem of low sampling and packing efficiency when using the current water quality sampling box. Utility Model Content

[0004] The utility model aims to provide a water quality sampling box, which is used to solve the technical problem that the sampling and packing efficiency of the existing water quality sampling box is low when it is used.

[0005] The technical solution of the utility model is achieved in this way:

[0006] A water quality sampling box comprises a box cover and a box body, wherein the box cover is rotatably connected to the box body, a storage bin is arranged in the box body, a box wheel is arranged at the bottom of the box body, a rotating mechanism is arranged on the inner side of the box cover, and the rotating mechanism comprises a water injection pipe, wherein the water injection pipe is connected to a water supply pipe, a water injection head is arranged at the end of the water supply pipe, a peristaltic pump for driving the water supply pipe is arranged on the top of the box cover, a diversion plate is connected to the bottom of the box cover by a connecting rod, a plurality of diversion units are arranged on the diversion plate, a rotating path of the water injection head passes through the top of each diversion unit, a plurality of placement positions are arranged in the storage bin, and each placement position corresponds to each diversion unit at the top.

[0007] As a preferred embodiment, the diversion unit includes a diversion groove on the top and a guide port on the bottom side, the diversion groove is connected with the guide port, and each guide port corresponds to each placement position on the bottom side.

[0008] As a preferred embodiment, the rotation connection between the box cover and the box body is located at the rear end, and the first locking device is provided at the front end of the box cover and the box body.

[0009] The first locking device is used to lock the sampling box.

[0010] As a preferred embodiment, a second locking device is provided on the side of the box cover and the box body, the first locking device includes a first locking block provided on the box cover and a first hook plate provided on the box body, and the first locking block cooperates with the first hook plate; the second locking device includes a second hook plate provided on the box cover and a second locking block provided on the box body, and the second locking block cooperates with the second hook plate.

[0011] The second locking device cooperates with the first locking device to lock the sampling box. The second locking device is arranged opposite to the first locking device to perform doubly locking on the side and front end of the sampling box.

[0012] As a preferred embodiment, a support rod is provided between the box cover and the box body.

[0013] As a preferred embodiment, a cache bottle is provided on the water delivery pipe, and the cache bottle is fixed on the outer side wall of the box body.

[0014] As a preferred embodiment, a partition is provided in the storage bin, and the storage bin is divided into a plurality of placement positions by the partition.

[0015] As a preferred embodiment, a placement base is provided in the storage bin, and a plurality of concave placement positions are provided on the placement base.

[0016] When the utility model is used, an empty sampling bottle is directly placed in the placement position, and the water delivery pipe will automatically fill the sampling water into each empty sampling bottle. The rotating mechanism drives the water injection pipe and the water injection head to rotate, and the sampling water is quantitatively injected into each sampling bottle in turn, thereby realizing automatic sampling and replacing the manual sampling method of sampling one bottle at a time.

[0017] The utility model utilizes a peristaltic pump to drive a water delivery pipe to deliver sample water.

[0018] At the initial stage of starting the peristaltic pump, when the water pipe connected to the inlet (here referred to as the inlet connecting pipe) is filled with water, the water flow usually cannot fill the inlet connecting pipe, and the inlet connecting pipe is filled with a large number of bubbles. If this directly enters the sampling bottle through the peristaltic pump, it is easy to cause inaccurate sampling measurement (the measuring sensor is usually set near the part where the pipe and the metering pump are connected).

[0019] This solution adds a cache bottle. When the peristaltic pump is activated, water enters the cache bottle from the inlet. Only when the cache bottle is full of water, the water in the cache bottle will enter the sampling box through the peristaltic pump. This can greatly reduce the amount of bubbles passing through the peristaltic pump, and even avoid bubbles in the fluid passing through the peristaltic pump, which can improve the accuracy of automated metering sampling.

[0020] The beneficial effects of the utility model are:

[0021] The utility model can be used to carry out water quality sampling and packing with high speed and high efficiency, which solves the technical problem of low sampling and packing efficiency when using the existing water quality sampling box, and has accurate measurement, thus avoiding the problem of inaccurate measurement of mechanized sampling.

A plurality of diverter units are arranged on the diverter plate 12, and the rotation path of the water injection head 21 passes through the top of each diverter unit, see Figure 5 A plurality of placement positions 15 are provided in the storage bin 19, and each placement position 15 corresponds to each diversion unit at the top.

[0035] The rotating mechanism here can only realize rotation on the horizontal plane. The market technology in this regard is very mature and can be used directly.

[0036] The flow diversion unit includes a diversion groove 20 at the top and a flow guide port 13 at the bottom. The diversion groove 20 is connected to the flow guide port 13. Each flow guide port 13 corresponds to each placement position 15 at the bottom.

[0037] The rotation connection between the box cover 1 and the box body 3 is located at the rear end, and the first locking device 6 is provided at the front end of the box cover 1 and the box body 3.

[0038] The first locking device 6 is used to lock the sampling box.

[0039] A second locking device 2 is provided on the side of the box cover 1 and the box body 3.

[0043] The storage bin 19 is provided with a partition 14, and the storage bin 19 is divided into a plurality of placement positions 15 by the partition 14, see Figure 3 In view of this design, another implementation is provided: a placement base is provided in the storage chamber 19, and a plurality of concave placement positions 15 are provided on the placement base, which can also achieve the effect of limiting the position of the sample bottle.

[0044] When the utility model is used, an empty sampling bottle is directly placed in the placement position 15, and the water delivery pipe 10 will automatically fill the sampling water into each empty sampling bottle, and the rotating mechanism 23 drives the water injection pipe 22 and the water injection head 21 to rotate, and the sampling water is quantitatively injected into each sampling bottle in turn, thereby realizing automatic sampling, replacing the manual sampling method of sampling one bottle at a time.

[0047] At the initial stage of starting the peristaltic pump 8, when water is taken in by the water pipe 10 connected to the inlet (referred to as the inlet connecting pipe here), the water flow usually cannot fill the inlet connecting pipe, and the inlet connecting pipe is filled with a large number of bubbles. If this directly enters the sampling bottle through the peristaltic pump 8, it is easy to cause inaccurate sampling measurement (the measuring sensor is usually set near the part where the pipe and the metering pump are connected).

[0048] This solution adds a buffer bottle 11. When the peristaltic pump 8 is activated, water enters the buffer bottle 11 from the inlet of the buffer bottle 11. Only when the buffer bottle 11 is full of water, the water in the buffer bottle 11 will enter the sampling box through the peristaltic pump 8. This can greatly reduce the amount of bubbles passing through the peristaltic pump 8, and even avoid bubbles in the fluid passing through the peristaltic pump 8, which can improve the accuracy of automated metering sampling.
