Description

Technical Field

[0001] The utility model relates to the technical field of sampling pumps, in particular to a suspended sampling pump. Background Art

[0002] A pump is a machine that transports fluids or increases the pressure of fluids. It transfers the mechanical energy of the prime mover or other external energy to the liquid, increasing the energy of the liquid. Pumps are mainly used to transport liquids such as water, oil, acid and alkali solutions, emulsions, suspension liquids, and liquid metals, and can also transport liquid-gas mixtures and liquids containing suspended solids. Pumps can usually be classified into three categories according to the working principle: positive displacement pumps, dynamic pumps, and other types of pumps. Currently, due to the limitations of the sampling environment for exhaust gas sampling from fixed pollution sources, most portable instruments are used, and the ultimate optimization goal of portable instruments is to make the instrument as light as possible without affecting the sampling quality.

[0003] The following problems exist in the prior art:

[0004] 1. For existing suspended sampling pumps, both the bottom and the head of the pump body are affected after entering the water. The head of the sampling pump is easily squeezed and deformed, and there is no device for fixing. The bottom discharge port is easily blocked, making it inconvenient to use.

[0005] 2. For existing suspended sampling pumps, the floating force is not obvious enough, resulting in the device tilting. Moreover, after the sampling pump enters the water, the sampling end is affected by buoyancy and cannot be fully in contact with the water surface, causing deviations in sampling. Summary of the Utility Model

[0007] A suspended sampling pump includes a base. A pump body is fixedly connected to the top of the base. A connecting plate is fixedly connected to the top of the pump body. An extraction mechanism is movably connected to the top of the connecting plate. A floating mechanism is sleeved on the outer wall of the pump body. A connecting mechanism is sleeved at the bottom of the pump body. A sewage discharge pipe is inserted into one side of the connecting mechanism.

[0008] The further improvement of the technical solution of the utility model lies in that: the extraction mechanism includes a mounting plate. The bottom of the mounting plate is movably connected to the top of the connecting plate. A plug connector is fixedly connected to the top of the mounting plate. Four liquid inlet pipes are fixedly connected to the top of the plug connector. A suction pipe is fixedly connected to the bottom of the mounting plate.

[0009] The further improvement of the technical solution of the utility model lies in that: the bottom of the suction pipe penetrates through the connecting plate and is inserted into the inside of the pump body.

[0010] A further improvement of the technical solution of the present utility model lies in that: the connecting mechanism includes a connecting end, the top of the connecting end is fixedly connected to the bottom of the pump body, a filter screen is arranged inside the connecting end, a floating plate is fixedly connected to the outer wall of the connecting end, and a connecting pipe is inserted into the outer ring of the floating plate.

[0011] A further improvement of the technical solution of the present utility model lies in that: one end of the connecting pipe is inserted into the floating plate and connected to the connecting end, and one end of the connecting pipe is threadedly connected to the sewage discharge pipe.

[0012] A further improvement of the technical solution of the present utility model lies in that: the floating mechanism includes a floating ring, a floating platform is connected through the floating ring, a connecting rod is fixedly connected to the top of the floating ring, and a support rod is fixedly connected to the bottom of the floating ring.

[0013] A further improvement of the technical solution of the present utility model lies in that: one end of the connecting rod is connected to the outer wall of the mounting plate, and the bottom of the support rod is fixedly connected to the floating plate.

[0014] Due to the adoption of the above technical solution, the technical progress achieved by the present utility model compared with the prior art is:

[0015] 1. The present utility model provides a suspended sampling pump. The inside of the pump body is connected to the extraction pipe, and the top of the extraction pipe is connected to the liquid inlet pipe, which is convenient for the liquid to be extracted through the pump body. The extraction pipe is connected to the plug connector, which is convenient to enter the water and can be protected to prevent the extraction pipe from being damaged by impact. The bottom of the pump body is connected to the connecting mechanism, so that the extracted liquid is transmitted here. In order to reduce the influence of large particles on liquid sampling and cause blockage inside the sewage discharge pipe, a filter screen is arranged inside the connecting mechanism, and the filter screen will not affect the detection result. The sewage discharge pipe is installed on one side of the pump body, which is convenient for the sampling pump to take liquid.

[0016] 2. The present utility model provides a suspended sampling pump. The outer wall of the pump body is sleeved with a floating mechanism. The main buoyancy of the floating mechanism is the floating ring. In order to make the buoyancy more obvious, a floating platform is connected inside the floating ring. The top of the floating ring is connected to the mounting plate through the connecting rod, and the bottom is connected to the floating plate through the support rod. The floating plate is installed close to the base. Just because of this, when the sampling pump is thrown into the water, it can float up reversely.
