Abstract
The utility model relates to an underwater water sampler releasing device, which is characterized in that a sampler holding box for holding the upper part of the sampler is provided, the sampler holding box is fixedly connected on a base, and a hole for the sampler to enter and go out vertically is arranged at the corresponding position of the bottom of the sampler holding box and the base; a nipple is arranged at the top of the sampler holding box, and is movably connected with the screw thread of a connecting rod; a plurality of symmetrically arranged holding frames fixedly connected with the outer wall of the sampler holding box are arranged on the base; a group of symmetrically arranged cranks are provided, the upper ends of the cranks are protruding bolt shaped, and are movably napped with holes and concave holes arranged at the corresponding positions on the sampler in the sampler holding box and the sampler holding box, the other ends of the cranks are connected with a pull rope together, pivots are arranged on the cranks and are articulated with the holding frames.
Description
One, technical field
The utility model relates to the equipment that is used for shallow lake and river deposit hydromining sample, and especially a kind of delivery device under water of pore water sampling thief is learned and environmental science with belonging to.
Two, background technology
Sampling is an important means of carrying out sediment and sediment-water termination water quality research under water, " the multi-cavity chamber dialysis formula sampling thief " that now is widely used is a kind of sediment pore water sampling thief by doctor RayHesslein of Columbia Univ USA invention in 1976, uses special term " Peeper " expression abroad.This sampling thief inserts sediment after osmotic equilibrium, but in-situ acquisition different depth sediment mesoporosity water, thus the content of desired substance in the analysis pore water is one of main equipment that obtains at present pore water.But owing to be subjected to the influence of water depth, this sampling thief is mainly used in wetland researchs such as shallow water (less than 1 meter) lakes and marhshes and river, limit to some extent for application than deepwater field, mainly be because when throwing in this sampling thief, over-borrowing is driven in the mud with weights such as hammers, and its insertion depth and vertical extent are often wayward, and waterborne number and the chamber exposure position of the chamber of this sampling thief in mud can not be fixed, so poor repeatability, influenced the representativeness of sampling precision.
Three, summary of the invention
The sample effect of the utility model in order to use above-mentioned Peeper sampling thief to obtain better designed a kind of delivery device under water that utilizes lever principle to be used to place water sampler, and its technical scheme is as follows:
The delivery device under water of water sampler, it is characterized in that being provided with one hold sampling thief top hold the device box, this is held the device box and is fixedly connected on base, the relevant position of holding device box bottom and base has the hole of the vertical turnover of sampling thief; Hold device box top and be provided with threaded connector, connect with the connecting rod screw thread is movable; Base is provided with and holds the bracing frame of several symmetric arrangement that the device outer box wall is fixedly connected; The crank of one group of symmetric arrangement is set, the upper end of crank is prominent bolt shape, is movably fastened with holding the device box and hold hole and the shrinkage pool that the corresponding position is provided with on the sampling thief in the device box, and the other end of crank is common to connect a stay cord, crank is provided with hinged point, is connected with bracing frame is hinged.Crank connects on the end of stay cord, does not also have the spring that connects firmly with base.Base can be plectane, and the import and export that the base center holds sampling thief also can be circular hole.
Advantage of the present utility model and effect: be applicable to that the depth of water is not more than waters such as the river of 5M, lake and vertically throws in sampling thief, need not frogman's operation; But sampling precision is improved in the chamber exposure number and the position of fixed sample device; Easy to carry, rational in infrastructure, be applicable to open-air scientific investigation and can make supporting approved product and use for the user with sampling thief.
Four, description of drawings
Fig. 1,2 is respectively master, the side view of existing Peeper sampling thief;
Fig. 3,4 is respectively master of the present utility model, vertical view.
Five, embodiment
With top shown in Fig. 1,2 is rectangular parallelepiped, and wall has grid hole, and the lower end is in the delivery device shown in the wedge shape sampling thief load map 3,4.Among Fig. 3,4, the shape of holding device box 7 is consistent with sampling thief, and size can be slightly larger than sampling thief.Holding device box 7 can be integrally welded with annular base plate 10 and four bracing frames 4, and the base center is offered circular hole and held the sampling thief turnover, is in order to reserve out the hydrospace, so that accelerate rate of sinking.Holding device box welded top has female adapter 2, with connecting rod 1 (can be made into the multistage removable jew, one meter every period, be suitable for the different depth of waters) the movable connection.
The prominent bolt of crank 3 upper ends snaps on the sampling thief in the end shrinkage pool 12 by holding on the device box hole 11, sampling thief is clamped in holds in the device box.5 is the hinged point that crank is connected with bracing frame, and 8 is the pulling force point of stay cord 6, and pulling force point 8 has the spring 9 that connects firmly with base plate 10.Spring 9 is adjusted into appropriate extended state before input, can guarantee the reliability of clamping sampling thief.During use, hand-held connecting rod 1 vertically puts down dispenser in water, and makes stay cord 6 be relaxed state, makes sampling thief enter sediment until base ring flat-plate plane contact sediment top layer, and input stops; Upwards spur stay cord 6, this moment, crank be center of circle motion with fulcrum 5, the shrinkage pool 12 of the prominent bolt disengaging in crank top sampling thief, on carry connecting rod 1 and make and hold the device box and separate with sampling thief, thereby realized the input under water of sampling thief.Than the hard area, can then should slow down rate of sinking for the ooze district for shale, prevent that the base ring flat-plate is pressed in the sediment by the downward application of force of connecting rod appropriateness.The utility model also can be used for other inputs of sampling apparatus under water, and the shape and the sampling thief coupling that only need to hold the device box get final product.
Claims (3)
1, the delivery device under water of water sampler, it is characterized in that being provided with one hold sampling thief top hold the device box, this is held the device box and is fixedly connected on base, the relevant position of holding device box bottom and base has the hole of the vertical turnover of sampling thief; Hold device box top and be provided with threaded connector, connect with the connecting rod screw thread is movable; Base is provided with and holds the bracing frame of several symmetric arrangement that the device outer box wall is fixedly connected; The crank of one group of symmetric arrangement is set, the upper end of crank is prominent bolt shape, is movably fastened with holding the device box and hold hole and the shrinkage pool that the corresponding position is provided with on the sampling thief in the device box, and the other end of crank is common to connect a stay cord, crank is provided with hinged point, is connected with bracing frame is hinged.
