Description

Technical Field

[0001] The utility model relates to the technical field of pressure gauges, in particular to a sprinkler irrigation pressure gauge. Background Art

[0002] Sprinkler irrigation is an irrigation method that uses a water pump and piping system or the height difference of a natural water source to spray water with a certain pressure into the air, and then scatters it into small droplets or forms mist and falls on plants and the ground. A pressure gauge refers to an instrument that uses an elastic element as a sensitive element to measure and indicate pressure higher than the ambient pressure. The pressure gauge uses the elastic deformation of the sensitive element (Bourdon tube, diaphragm box, bellows) inside the gauge, and then the conversion mechanism of the movement inside the gauge transmits the pressure deformation to the pointer, causing the pointer to rotate to display the pressure.

[0003] Patent announcement number CN203275020U discloses a grouting pressure gauge protection device, including a hydraulic transmission device and a tee pipe, wherein one interface of the tee pipe is installed with the hydraulic transmission device, a pressure reading device is arranged above the hydraulic transmission device, and the other two interfaces of the tee pipe are respectively connected to the return slurry pipe, and a gate valve is arranged on the return slurry pipe. The utility model is a grouting pressure gauge protection device, which effectively solves the problem that the pressure gauge is easily damaged and scrapped when it is directly connected to the return slurry pipe. The device has a simple structure and is economical and applicable.

[0004] Although the prior art CN203275020U has many benefits during use, it still has the following problems: it lacks a cleaning structure for the pressure gauge. Since the pressure gauge is used in a relatively humid environment, water mist will adhere to the surface of the pressure gauge, forming watermarks and scale on the surface of the pressure gauge, affecting the staff's observation clarity of the pressure gauge data. Utility Model Content

[0005] The utility model aims to provide a sprinkler pressure gauge to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sprinkler pressure gauge, comprising a connecting pipe, a fixing frame and a pressure gauge body, the outer walls of both sides of the connecting pipe are installed with bearings, the outer walls of the bearings are rotatably installed with a connecting pipe, a fixing frame is installed on one side of the outer wall of the upper end of the connecting pipe, a driven wheel is rotatably installed inside the fixing frame, and a connecting plate is installed on the outer wall of one end of the driven wheel.

[0007] When using a sprinkler pressure gauge in the technical solution, the liquid is pressurized by an external liquid pump and flows inside the connecting pipe, and the pressure gauge body detects the pressure data of the liquid. When the liquid flows, the impeller is driven to rotate in a circle, thereby driving the driven wheel to rotate in a circle through the connecting pipe and the transmission belt. The connecting plate rotates in the same direction as the driven wheel, and the outer wall of the pressure gauge body is cleaned by a scraper to prevent water mist from accumulating on the outer wall of the pressure gauge body, thereby ensuring the relative cleanliness of the outer wall of the pressure gauge body.

[0008] Preferably, flanges are installed on the outer walls of both ends of the connecting pipe, and circularly arranged fixing holes are provided inside the flanges.

[0009] The external pipeline can be connected to the connecting pipe through the flange and the fixing hole to ensure the connection stability between the external pipeline and the connecting pipe.

[0010] Preferably, a support frame is installed on the inner wall of the connecting pipe, and an impeller is rotatably installed on the outer wall of one side of the support frame, and the impeller is located inside the connecting pipe.

[0011] The flow of liquid inside the connecting pipe can drive the impeller to rotate in a circle and drive the connecting pipe to rotate in a circle.

[0012] Preferably, a pressure gauge body is plugged and installed on one side of the outer wall of the upper end of the connecting pipe, and the pressure gauge body is connected to the inside of the connecting pipe.

[0013] The pressure gauge body can detect the liquid pressure data inside the connecting pipe.

[0014] Preferably, a transmission belt is provided on the outer wall of the driven wheel, and the driven wheel is connected to the connecting pipe through the transmission belt.

[0015] The transmission belt ensures that the driven wheel and the connecting pipe rotate in the same direction.

[0016] Preferably, a scraper is fixedly attached to the outer wall of one side of the connecting plate, and the scraper is in contact with the outer wall of the pressure gauge body.

[0017] The scraper can scrape and clean the outer wall of the pressure gauge body.

[0018] Preferably, the inner diameter of the connecting pipe is larger than the outer diameter of the connecting pipe, and the connecting pipe is located outside the connecting pipe.

[0019] Compared with the prior art, the utility model has the following beneficial effects: the utility model achieves the effect of cleaning the pressure gauge body by arranging an impeller, a transmission belt and a scraper. The liquid is pressurized by an external liquid pump and flows inside the connecting pipe, and the pressure gauge body detects the pressure data of the liquid. When the liquid flows, the impeller is driven to rotate in a circle, thereby driving the driven wheel to rotate in a circle through the connecting pipe and the transmission belt. The connecting plate rotates in the same direction as the driven wheel, and the outer wall of the pressure gauge body is cleaned by the scraper to avoid water mist from accumulating on the outer wall of the pressure gauge body, thereby ensuring the relative cleanliness of the outer wall of the pressure gauge body, avoiding the formation of watermarks and scale on the surface of the pressure gauge body, and ensuring the clarity of the staff's observation of the pressure gauge data.
