The utility model relates to a self-sealing sample retention bottle and a sampler, wherein the sample retention bottle comprises a bottle body, a top opening arranged at the top of the bottle body, a water passing opening arranged at the bottom of the bottle body and a silica gel valve arranged on the top opening; the utility model discloses a stay appearance bottle all reserves the mouth at the upper and lower both ends of bottle, installs the silica gel valve on the top mouth on upper portion, when pouring water or discharging the water in the bottle in to the bottle through crossing the mouth of a river, because the effect of the inside and outside pressure differential in the bottle, the silica gel valve just can be opened, and the inside and outside pressure of balanced bottle can be with the liquid evacuation in the bottle when guaranteeing the drainage, and when intaking, the sample that can guarantee to gather simultaneously is full of whole bottle.
Description
Technical Field
The utility model relates to a water sample check out test set field specifically is a sample bottle and sample thief are stayed to self sealss.
Background
In the field of water quality detection, a water pump is generally required to pump water in a water area to be detected into a sample retention bottle for storage, and when data validity examination is required, a water sample in the sample retention bottle is taken out for detection; when not needed, the sample bottle is left empty after one cycle. The existing sampler does not have an emptying function for sampling, does not have a sealing function for emptying, and cannot meet the requirements of the current small-sized station and the shore station due to the factors of complex mechanism, high cost, large size and the like.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a simple structure is provided, self sealss that can realize the evacuation function are stayed appearance bottle and sample thief.
The utility model adopts the technical proposal that: a self-sealing sample retention bottle comprises a bottle body, a top opening arranged at the top of the bottle body, a water passing opening arranged at the bottom of the bottle body and a silica gel valve arranged on the top opening.
Furthermore, the silica gel valve adopts a cross-shaped silica gel valve, and the silica gel valve is connected with the top opening of the sample-reserving bottle in a sealing manner, so that the top opening of the sample-reserving bottle is in a sealing state.
Furthermore, the water outlet at the bottom of the sample reserving bottle is connected with the electromagnetic valve and is normally in a normally closed state, so that the sample in the sample reserving bottle can be kept in a sealed storage state. By switching the state of the electromagnetic valve, the sample collection or the emptying of the sample in the sample retention bottle can be realized.
A sampler comprises a shell, a sample retention bottle arranged in the shell, and a sampling device communicated with the sample retention bottle.
Furthermore, the lower extreme of staying the appearance bottle is provided with the connecting pipe, the connecting pipe cooperatees with crossing the water mouth, get sampling device and connecting pipe intercommunication.
Furthermore, a sealing ring is arranged between the connecting pipe and the water passing port.
Furthermore, a groove is formed in the connecting pipe, and the sealing ring is embedded in the groove.
Furthermore, the sample retention bottle is arranged in the middle of the shell, the sampling device is located below the sample retention bottle, and the control part is located above the sample retention bottle.
Further, get sampling device and include sampling pump and sampling pump, sampling pump and water intaking pump all pass through the pipeline cooperation with the connecting pipe.
Furthermore, a valve is arranged on the pipeline close to the connecting pipe.
The utility model discloses an actively the effect does: the utility model discloses a stay appearance bottle all reserves the mouth at the upper and lower both ends of bottle, installs the silica gel valve on the top mouth on upper portion, and the mouth of a river and the solenoid valve of crossing of bottom are connected, and the sample in the appearance bottle can be realized staying to normally closed state sealed the saving. When intaking or discharging the water in the bottle through crossing the mouth of a river in to the bottle, need switch over the state of solenoid valve, realize through getting the sampling pump, because the effect of the interior external pressure difference of bottle, the silica gel valve just can be opened, and the internal and external pressure of balanced bottle can be with the liquid evacuation in the bottle when guaranteeing the drainage. When the pressure inside and outside the bottle body is consistent, the silica gel valve is closed, the sealing of the top opening is realized, the problem that after a water sample of the shore station is fully collected, a maintainer needs to process the water sample on site is solved, the working strength of the maintainer is reduced, and the maintenance frequency of the shore station is reduced.
Drawings
FIG. 1 is a schematic view of the structure of a sample retention bottle of the present invention;
FIG. 2 is a schematic view of the sampler of the present invention;
fig. 3 is a partially enlarged view of a portion a in fig. 2 according to the present invention.
Detailed Description
As shown in the attached drawing 1, the utility model discloses a leave appearance bottle includes bottle 1, sets up respectively at the top mouth 9 and the water gap 3 at bottle 1 upper and lower both ends and sets up the silica gel valve 2 on top mouth 9, and water gap 3 is used for conveying the water sample and also is used for the water sample in the clean-up bottle 1 simultaneously in to bottle 1.
The silica gel valve 2 adopts a cross silica gel valve which is similar to a bottle cap of a scream beverage, when a certain pressure difference exists between the inside and the outside of the bottle body, the silica gel valve 2 can be opened, and when no pressure difference exists, the silica gel valve 2 is closed, so that the sealing state inside the bottle body is ensured. When pressure difference exists between the inside and the outside of the bottle body 1, the silica gel valve 2 is opened to balance the pressure of the gas inside and outside, so that a water sample can enter the bottle body 1 or be completely emptied.
As shown in fig. 2 and 3, the sampler of the present invention comprises a housing 10, a sample-reserving bottle disposed in the middle of the housing 10, a sampling device disposed in the lower part of the housing 10 and connected to the sample-reserving bottle, and a control unit 8 disposed in the upper part of the housing 10. The control section 8 has the same structure as the conventional sampler.
The sample bottle sample collection device is characterized in that a bearing plate 11 is arranged in a shell 10, a sample retention bottle is placed on the bearing plate 11, a connecting pipe 4 is arranged on the lower end face of the bearing plate 11, the inner diameter of the connecting pipe 4 is matched with the outer diameter of a water passing port 3 in the radial direction, two rubber sealing rings 5 are arranged between the connecting pipe 4 and the water passing port 3, and the rubber sealing rings 5 are embedded in a groove 6 in the inner wall of the connecting pipe 4. A valve is arranged on the lower pipeline of the connecting pipe 4, and then the pipeline is respectively connected with the sampling pump 7 and the sampling pump
