Description

Technical Field

[0001] The utility model relates to the technical field of powder silo material level measuring equipment, in particular to an automatic powder silo material level measuring equipment for water conservancy projects. Background Art

[0002] Powder silos are widely used in mixing plants, mixing towers, and other facilities to store cement and fly ash. Currently, there are two methods for measuring the material level in powder silos: one is to use the manufacturer's own material level sensor to display the approximate material level; the other is for the operator to climb a ladder to a certain point outside the storage silo and judge the material level by knocking on the outer wall of the storage silo.

[0003] Existing technology allows workers to determine material levels by tapping the outer wall of the silo. However, this requires workers to repeatedly climb up and down ladders, which is labor-intensive, dangerous, and has low accuracy. Therefore, those skilled in the art have provided an automated level measurement device for powder silos in hydraulic engineering projects to address the problems raised in the above background technology. Utility Model Content

[0004] The purpose of the utility model is to provide an automated powder silo level measuring device for a water conservancy project, so as to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A material level measuring device for an automated powder silo of a water conservancy project comprises a powder barrel, a base plate, a measuring rope, a support frame and a measuring ball, wherein the upper end of the powder barrel is fixedly connected to the support frame, one side of the lower end of the powder barrel is fixedly connected to the base plate, a first servo motor is fixedly mounted on the base plate, a power output end of the first servo motor is fixedly connected to a first rotating shaft, a first rope drum is fixedly connected to the first rotating shaft, a first pulley is arranged above the first rope drum, a second pulley is arranged on the right side of the first pulley, a third pulley is arranged below the second pulley, a measuring ball is arranged below the third pulley, a second servo motor is fixedly mounted on the support frame, a power output end of the second servo motor is fixedly connected to the second rotating shaft, a second rope drum is fixedly connected to the second rotating shaft, a connecting rope is arranged on the second rope drum, wherein one end of the connecting rope is fixedly connected to the second rope drum, and the other end of the connecting rope is fixedly connected to the second pulley.

[0007] As a further solution of the present invention: one end of the measuring rope is fixedly connected to the first rope drum, and the other end of the measuring rope is fixedly connected to the second pulley, and the measuring rope passes through the first pulley, the second pulley and the third pulley.

[0008] As a further solution of the present invention: a first steel wire rope is provided on the first pulley, wherein the upper end of the first steel wire rope is fixedly connected to the top of the support frame, and the lower end of the first steel wire rope is fixedly connected to the first pulley.

[0009] As a further solution of the present invention: a second steel wire rope is provided on the second pulley, wherein the upper end of the second steel wire rope is fixedly connected to the top of the support frame, and the lower end of the second steel wire rope is fixedly connected to the second pulley.

[0010] As a further solution of the present invention: a support rod is fixedly connected to the upper surface of the base plate, and a controller is fixedly installed on the upper end of the support rod, wherein the controller can control the opening and closing of the first servo motor and the second servo motor.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. Starting the first servo motor can pull the measuring rope and the measuring ball up and down, and starting the second servo motor can pull the third pulley, the measuring rope and the measuring ball toward the second rope drum, so that the measuring ball hits the powder barrel. This can automatically complete the knocking task without manual climbing and knocking, saving manpower, improving work efficiency and safety.

[0013] 2. The material level inside the silo can be roughly determined by knocking on the inner wall. Based on the feedback of the knocking sound, the change in the distance between the powder and the knocker can be sensed, thereby inferring the approximate height of the material level. Knocking on the outer wall of the silo cannot directly measure the material level like knocking on the inner wall. In addition, knocking on the inner wall can provide preliminary information about the density and accumulation status of the powder. The echo of the knocking sound can reflect the looseness and accumulation of the powder. BRIEF DESCRIPTION OF THE DRAWINGS
