[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Figures 1-6As shown, this utility model provides a metal scraper flow meter with preheating function, including a metal scraper flow meter body 1. A counter 2 is fixedly installed on the top of the metal scraper flow meter body 1 for use with it. The upper end of the metal scraper flow meter body 1 is provided with a cleaning mechanism 3 and a fixing mechanism 4 for use with the counter 2. The metal scraper flow meter body 1 and the counter 2 work together. The metal scraper flow meter body 1 has a preheating function and a function to prevent dust and water from entering, thereby enabling the internal cavity to be heated, which in turn enables the condensing medium to change from a condensed state to a working state, thereby improving the measurement accuracy and equipment adaptability. This is prior art and will not be described in detail here. The cleaning mechanism 3 includes a base frame 31. The base 31 can be fixedly mounted on the upper end of the metal scraper flowmeter body 1, and an L-shaped plate 32 is fixedly connected to the base 31. Symmetrically distributed insertion rods 311 are fixedly installed on the upper end of the metal scraper flowmeter body 1. Symmetrically arranged insertion holes 312 are provided on the base 31, and the insertion rods 311 can be slidably inserted into the insertion holes 312. The cooperation between the insertion rods 311 and the insertion holes 312 can effectively improve the installation stability of the base 31 and the metal scraper flowmeter body 1. An electric push rod 33 is fixedly installed on one side of the top of the L-shaped plate 32, and the output end of the electric push rod 33 slides through the L-shaped plate 32 and is fixedly connected to a brush plate 34 at its end. The brush plate 34 can contact the screen of the counter 2, and symmetrically arranged insertion holes 312 are fixedly installed on the top of the brush plate 34. A guide rod 35 is provided, which slides through an L-shaped plate 32. Symmetrically distributed guide holes 313 are provided at the end of the L-shaped plate 32, and the guide rod 35 slides through the guide holes 313. The cooperation between the guide rod 35 and the guide holes 313 limits and guides the movement of the brush plate 34. A water tank 36 is fixedly inserted into one side of the base frame 31, and a water pump 37 is fixedly installed at the top of the water tank 36. Both the electric push rod 33 and the water pump 37 are controlled by a PLC control module, and the relevant circuit connections are existing technology, which will not be elaborated here. The lower end of the water pump 37 has a cooperating inlet pipe 38 and an outlet pipe 39. The inlet pipe 38 is fixedly inserted into the water tank 36, and the outlet pipe 39 is fixedly inserted into the L-shaped plate 32. The end of the 9 is connected to a spray pipe 310 that works with the brush plate 34. The top of the water tank 36 is connected to a water supply pipe 314, and a pipe cap 315 is detachably provided on the water supply pipe 314. The use of the water supply pipe 314 and the pipe cap 315 ensures the replenishment of water in the water tank 36 and normal extraction. The bottom of the inner cavity of the water tank 36 is a low inclined structure near the bottom of the inlet pipe 38. A through hole 316 is opened through the upper end of the water tank 36, and the inlet pipe 38 is fixedly inserted into the through hole 316. A through hole 317 is opened through the lower end of the L-shaped plate 32, and the outlet pipe 39 is fixedly inserted into the through hole 317. The use of the through hole 316 and the through hole 317 ensures the stable connection of the inlet pipe 38 and the outlet pipe 39.

[0021] By adopting the above technical solution, when in use, the pipe cover 315 is removed and an appropriate amount of water is introduced into the water tank 36 through the water supply pipe 314. Then the pipe cover 315 is reset. During subsequent use, the electric push rod 33 and the water pump 37 can be activated, which can drive the brush plate 34 to reciprocate and lift. The water in the water tank 36 can be drawn from the inlet pipe 38 into the outlet pipe 39 and introduced into the spray pipe 310. The introduced water will then be guided by the spray pipe 310 to the screen of the counter 2.

[0022] The fixing mechanism 4 includes a screw 41 and a bracket 42. The screw 41 is fixedly installed on the base frame 31 and has a symmetrical structure. Both ends of the bracket 42 are provided with a locking hole 43. The inner wall of the bracket 42 can fit against the upper outer wall of the metal scraper flow meter body 1. The screw 41 can move through the locking hole 43 and a matching nut 44 can be threaded onto the screw 41.

[0023] By adopting the above technical solution, when using it, hold the base frame 31 and put it on the upper end of the metal scraper flow meter body 1 until the insertion rod 311 is fully inserted into the corresponding insertion hole 312. Then, put the card holder 42 on the upper end of the metal scraper flow meter body 1 and let the screw 41 pass through the corresponding card hole 43. Then, thread the two nuts 44 onto the two screws 41 in sequence until the nuts 44 tightly abut against the card holder 42.

[0024] Working principle: When in use, hold the base frame 31 and put it on the upper end of the metal scraper flow meter body 1 until the insertion rod 311 is fully inserted into the corresponding insertion hole 312. Then put the bracket 42 on the upper end of the metal scraper flow meter body 1 and let the screw 41 pass through the corresponding bracket hole 43. Then, thread the two nuts 44 onto the two screws 41 in turn until the nuts 44 tightly abut against the bracket 42.

[0025] Afterwards, the pipe cover 315 is removed and an appropriate amount of water is introduced into the water tank 36 through the water supply pipe 314. Then, the pipe cover 315 is reset. During subsequent use, the electric push rod 33 and the water pump 37 can be activated, which can drive the brush plate 34 to reciprocate and lift. The water in the water tank 36 can be drawn from the inlet pipe 38 into the outlet pipe 39 and introduced into the spray pipe 310. The introduced water will then be guided by the spray pipe 310 to the screen of the counter 2. This, in conjunction with the use of the brush plate 34, can conveniently and effectively clean the screen of the counter 2, preventing the screen of the counter 2 from becoming dusty and affecting the accurate reading of the operator.

Secondly, the circuits, electrical components, and modules involved are all prior art, which can be fully implemented by those skilled in the art, and need not be elaborated upon. Furthermore, the scope of protection of this utility model does not involve improvements to the software. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, then this utility model also intends to include these modifications and variations.
