Description

I

The invention relates to sampling devices, in particular to devices for sampling bottom pumps.

A batometer is known that contains a mesh box with inlet and outlet openings, a steering wheel, a concave bottom, and an inclined mesh shield l.

The disadvantage of such a batometer is that with intensive movement of bottom pumps the rear part of it is completely filled and subsequent particles of the pumps are either carried out through the outlet or bypassing the batometer from the sides due to the occurrence of a backwater before the batometer.

The closest technical solution is a bathometer containing a mesh box with inlet and outlet openings, a mesh shield, a corrugated bottom with flanges, a collection of samples, nozzles, inclined

mounted at the top of the inlet, and the steering wheel 2.

The disadvantages of this bathometer are that the bottom of the sample collection is made flat and, when the batometer is installed at the bottom of the river, the lower part of the inlet can be lifted and these pumps pass under the bathometer, and the implementation of the mesh flap leads to a flatness of misses the inlet.

In addition, at high speeds and large depths it is difficult to install the batometer with the help of rods, as well as to hold it in the desired position.

The purpose of the invention is to increase the representativeness of sampled data of these pumps.

Claims (2)

This goal is achieved by the fact that the batometer containing a mesh box with inlet and outlet openings, a mesh shield, a corrugated bottom with sides, a collection of samples, a nozzle obliquely mounted at the top of the inlet, cables and a rudder, is provided with a guide tray with an elastic plate, mounted on its end, the sample collection is made in the form of a triangular prism and is equipped with air visors, and the mesh shield is made spherical. It is advisable to use a batometer with additional fastening cables, current is set at the bottom of the inlet. FIG. 1 shows the bathometer, general view; in fig. 2 - the same, top view. The batometer consists of a mesh shield 1 with an inlet 2 and an outlet 3 apertures, a spherical mesh shield A, hinged above the inlet 2, corrugated in the longitudinal direction of the bottom 5 with flanges 6, a collection of 7 samples, made in the form of a Triangular prism with baffles 8, a nozzle 3 obliquely mounted in the upper part of the inlet 2 and connected with a hose 10 to a pump for supplying pressurized water (not shown). The batometer is equipped with a guide tray 11 with an elastic plate 12 fixed to the end of the tray 11, Mesh shchi 1 is equipped with a stabilizing rudder 13 and cables H, and for holding the batometer in the flow are additional fastening cables 15 fixed on the guide chute 11 using staples 16. The design of the bathometer provides for a closer connection with the bottom the support, the implementation of the spherical mesh panel allows for the removal of particles of pumps bouncing off the guide tray, the bouncing hoods of the sample collection prevent particles from being raised when the batometer is raised, and They test the stability of the bathometer in the stream. The device works as follows. With the help of cables, the batometer is lowered to the bottom of the river, stabilized in its flow by the rudder 13 and held with the help of additional fixing cables 15. Bottom pumps fall on the elastic plate 12, which serves to more closely match the bathometer to the bottom of the river, then pass along the guide tray 11, which improves the entry of particles of bottom pumps into the inlets 2 due to a decrease in the angle of entry and moves along the corrugated bottom 5 to the triangular collection of samples 7, while the sides 6 prevent particles from being removed from the mesh box 1. Particles digits together by guide tray 11 and fed into the inlet 2 After impact with the inclined mesh spherical flap. The spherical shape i prevents the particles from rebounding past the inlet 2. At the end of the sampling session, the batometer rises to the surface with cables, while the baffles 8 prevent the washing out of particles from the collection of 7 samples. Collection 7 of samples is separated from the bathometer and sent to the laboratory. It is advisable to use a bathometer for hydrometric work on mountain rivers, where there are high flow rates. The effectiveness of the introduction of the bathometer is seen in that it makes it possible to more accurately measure the flow rate of bottom pumps, which reduces the volume of hydrometric work, since there is no need for repeated constipation. Claim 1. A bathometer comprising a mesh box with inlet and outlet openings, a mesh shield, a corrugated bottom with rims, a sample collector, a nozzle obliquely mounted in the upper part of the inlet, cables and a steering wheel, characterized in that, in order to increase the representativeness sampled bottom pumps, it is equipped with a guide chute with an elastic plate attached to its end, the sample collection is made in the form of a triangular prism and equipped with fender visors, and the mesh shield is spherical. , 2. The batometer according to claim 1, about tl and h ay u and with the fact that it is equipped with additional mounting cables. 593QOA76 and the guide tray is set to,. 1.
