Description

Technical Field

[0001] The utility model belongs to the technical field of water pollution control, and specifically relates to a water body sampling and filtering mechanism. Background Art

[0002] As we all know, water is the source of life for all things. When the pollutants entering the water body exceed the environmental capacity of the water body or the self-purification capacity of the water body, the water quality deteriorates, thus destroying the original value and function of the water body. This phenomenon is called water pollution. There are two reasons for water pollution: one is natural and the other is man-made. Water pollution caused by special geological conditions that lead to the large-scale enrichment of certain chemical elements, the production of certain harmful substances by natural plants when they decay, and the flow of various substances into the water body after rain falls to the ground, all belong to natural pollution.

[0003] In the process of water pollution control, water sampling is required to understand the actual situation of water pollution. After water sampling, the sample water may be mixed with aquatic plants, particulate matter, etc. These substances will affect the subsequent water body detection. Therefore, the sample water needs to be filtered, and the existing water body filtration mechanism has a relatively simple structure. It only actively filters through the set filter and uses the gravity of water to filter. The filtration efficiency is relatively low, and the aquatic plants and particulate matter in the water will gather on the surface of the filter and affect the circulation of water, thereby affecting the filtration efficiency. Utility Model Content

[0004] The purpose of the utility model is to provide a water sampling and filtering mechanism to solve the problem that the existing water filtering mechanism proposed in the above background technology has a relatively simple structure, and only performs active filtering through a set filter screen, using the gravity of water to filter, and the filtering efficiency is relatively low, and aquatic plant particles in the water body will gather on the surface of the filter screen, affecting the circulation of water, thereby affecting the filtering efficiency.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a water sampling and filtering mechanism comprises a filter housing, a filter housing cover is installed on the upper surface of the filter housing through a lock buckle, a cylinder is fixedly installed on the upper surface of the filter housing cover, a pressure plate is fixedly installed on the end of the piston rod of the cylinder, an inlet pipe is installed through the upper surface of the filter housing cover, one end of the inlet pipe located in the filter housing is connected and installed with a telescopic hose, a circular hole is opened on the pressure plate, one end of the telescopic hose away from the inlet pipe is connected with the circular hole, an outlet pipe is installed through the lower surface of the filter housing, and the inner wall of the filter housing is fixedly installed A support frame is provided, a filter screen is movably provided on the upper surface of the support frame, an inspection door is movably provided on the side of the filter housing, a plurality of rotating shafts are rotatably installed in the filter housing and the plurality of rotating shafts cooperate with each other, a motor is fixedly installed on the side of the filter housing, the output shaft of the motor is fixedly connected to the rotating shaft at the corresponding position, a plurality of discs are eccentrically fixedly installed on the outer surface of the rotating shaft, a plurality of support plates are fixedly installed on the inner wall of the filter housing, a plurality of sliding columns are slidably installed on the support plates, the bottom end of the sliding column cooperates with the disc, and a rubber knocking ball for knocking the filter screen is fixed on the top of the sliding column.

[0006] By adopting the above scheme, a cylinder is set to be used in conjunction with a pressure plate. After the water body is added to the inside of the filter shell, when the filter screen is actively filtered by using the gravity of the water, the cylinder piston rod extends to drive the pressure plate to move downward, thereby pushing the water body to press downward quickly, thereby passively filtering the water body and effectively improving the filtration efficiency. By setting a rotating shaft to be used in conjunction with an eccentrically set disc and a sliding column, the rubber knocking ball can be driven to move up and down continuously, thereby continuously knocking the filter screen, effectively avoiding the phenomenon of water plants and other particulate matter gathering on the filter screen surface to cause blockage, effectively ensuring the smooth flow of water, and thereby ensuring the smooth and orderly progress of the filtration operation.

[0007] In the above solution, it should be noted that the cylinder and the motor are both electrically connected to an external power source. As a preferred embodiment, a plurality of guide rods are slidably mounted on the filter housing cover, and the bottom ends of the guide rods are fixedly connected to the upper surface of the pressure plate.

[0008] By adopting the above scheme, when the cylinder piston rod is extended and retracted to drive the pressure plate to move up and down, the pressure plate will reach the guide rod and move up and down synchronously. The guide rod can be used to guide the up and down movement of the pressure plate, so that the pressure plate is not prone to tilting when moving up and down, thereby improving the movement stability.

[0009] As a preferred embodiment, the peripheral side surfaces of the pressure plate and the filter screen are both provided with mounting grooves, and sealing rings are pasted in the mounting grooves, and the sealing rings are closely arranged inside the filter housing.

[0010] By adopting the above scheme, the sealing ring on the pressure plate can prevent water from entering the space above the pressure plate, and the sealing ring on the filter can ensure that water can only be filtered through the filter, and the sealing ring can ensure a good sealing effect.

[0011] As a preferred embodiment, a plurality of fixing screws are fixedly installed on the lower surface of the filter, a plurality of through holes for the fixing screws to pass through are opened on the support frame, nuts are threadedly installed on the outer surface of the fixing screws, and the nuts are fitted on the lower surface of the support frame.

[0012] By adopting the above solution, the fixing screws are used in conjunction with the nuts to lock the filter screen and the support frame, thereby facilitating the subsequent disassembly and assembly of the filter screen.

[0013] As a preferred embodiment, a spring is sleeved on the outside of the sliding column, and two ends of the spring are fixedly connected to the supporting plate and the opposite surfaces of the rubber knocking ball respectively.

[0014] By adopting the above solution, the setting of the spring can ensure that the rubber knocking ball can knock the filter screen quickly and stably.

[0015] As a preferred embodiment, a pulley is fixedly mounted on the outer surface of the rotating shaft, and a belt is drivingly connected between two adjacent pulleys.

[0016] By adopting the above solution, the pulley and the belt are used in combination, so that multiple shafts can rotate synchronously without the need to be equipped with multiple motors.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] The water sampling and filtering mechanism is used by setting a cylinder in conjunction with a pressure plate. After the water is added to the filter housing, the filter screen is used in conjunction with the gravity of the water for active filtration. The cylinder piston rod extends to drive the pressure plate to move downward, thereby pushing the water to move downward quickly, thereby passively filtering the water and effectively improving the filtration efficiency.

[0019] The water sampling and filtering mechanism is used by setting a rotating shaft in conjunction with an eccentrically set disc and a sliding column, which can drive the rubber knocking ball to move up and down continuously, and then can continuously knock on the filter, effectively avoiding the phenomenon of water plants and other particulate matter gathering on the filter surface to cause blockage, effectively ensuring the smooth flow of water, and thus ensuring the smooth and orderly progress of the filtration operation.

[0027] A plurality of guide rods 19 are slidably mounted on the filter shell cover 2, and the bottom ends of the guide rods 19 are fixedly connected to the upper surface of the pressure plate 4. When the piston rod of the cylinder 3 is extended and retracted to drive the pressure plate 4 to move up and down, the pressure plate 4 will reach the guide rods 19 and move up and down synchronously.
