For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0018] As shown in the figure, an online position detection device for a liquid suction gun is used to be sleeved on the suction gun 6, including a shell 1, the shell 1 is an integrally formed structure, the shell 1 includes a top 11 and a bottom 12, the opening of the bottom 12 is larger than the opening of the top 11; the top 11 is connected to a clamping component 2, the clamping component 2 includes a nut 22 and a silicone ring 23 tightly attached to the inside of the nut; the top 11 and the clamping component 2 are coaxially arranged, the suction gun 6 can pass through the clamping component 2 and the shell 1 in turn, a travel switch 3 is arranged inside the shell 1, the travel switch 3 is suspended on the inner wall of one side of the top 11, and a travel switch 3 is also arranged on the bottom 12 There is a pressure plate 4, and the suction gun 6 will first pass through the pressure plate 4 before passing through the shell 1, and the inner surface of the pressure plate 4 is in contact with the outer surface of the suction gun 6; the pressure plate 4 can be an annular plate, and the annular pressure plate 4 is sleeved on the suction gun 6 and can move up and down relative to the suction gun 6; an elastic member 5 is provided in the shell 1, the top of the elastic member 5 is connected to the top 11, and the bottom of the elastic member 5 is against the pressure plate 4. When the suction gun is in place, the pressure plate 4 contacts the travel switch 3 to compress the elastic member 5. After the suction gun operation is completed, the pressure plate 4 is separated from the tank opening, and the elastic member 5 rebounds and the pressure plate 4 returns to the bottom 12. The elastic member 5 can be a spring or a telescopic bellows.
[0019] like Figure 2 As shown, in the initial state, the bottom of the travel switch 3 is not in contact with the pressure plate 4, the outer side of the pressure plate 4 is in contact with the upper end of the bottom 12, and the part of the bottom surface of the pressure plate 4 that does not overlap with the bottom 12 is exposed and can be in contact with the opening of the tank body. The pressure plate 4 can be placed stably on the bottom 12. When the bottom of the suction gun is inserted into the tank body, the opening of the tank body can support the bottom surface of the pressure plate 4 and push the pressure plate 4 to separate from the bottom 12 and move upward, so that the upper end of the pressure plate 4 contacts the bottom of the travel switch 3, thereby triggering the travel switch 3.
[0020] When in use, the position of the position detection device installed on the suction gun 6 needs to be adjusted according to the depth of the tank body, so that the distance from the bottom end of the travel switch 3 to the bottom end of the suction gun 6 is not less than the distance between the pressure plate 4 and the bottom of the tank body. Figure 1 As shown, the longitudinal height from the bottom of the travel switch 3 to the bottom of the suction gun 6 is H, and the thickness of the pressure plate 4 is T, that is, H ≥ T + tank depth. This not only ensures that the bottom of the suction gun 6 is close to the bottom wall of the tank, but also the tank opening can push the pressure plate 4 to the extent of abutting against the bottom of the travel switch 3. After determining the position of the position detection device on the suction gun, the position detection device is fixed on the suction gun 6 through the clamping component 2, and the suction gun 6 is inserted from the tank opening. It can be started after the travel switch 3 prompts. The staff does not need to determine whether the suction gun is in place every time, which improves work efficiency.
[0021] When the device of the utility model is used, the depth of the working tank body is first pre-judged, and the position detection device is installed in a suitable position. The suction gun passes through the clamping component 2, the top 11 and the pressure plate 4 in sequence. When the length of the bottom of the suction gun reaches the requirement, the position detection device is fixed on the suction gun through the clamping component 2, and the nut 22 is tightened to fix it. The staff puts the suction gun 6 with the fixed position detection device into the opening of the tank body. When the bottom of the suction gun 6 contacts the bottom wall of the tank body, the tank body opening pushes the pressure plate 4 to the bottom of the travel switch 3 and triggers the travel switch 3. When the suction gun is put into the tank body, the tank body opening pushes the pressure plate 4 upward, and the pressure plate 4 changes from not contacting the travel switch 3 to contacting the bottom of the travel switch 3, triggering the travel switch 3. The travel switch 3 gives a prompt. When the staff sees the prompt, they can open the suction gun to operate. After completing the suction operation, the suction gun is closed and taken out, and the pressure plate 4 is separated from the travel switch 3.
[0022] When the liquid level is high, material splashes may occur at the material port, causing external environmental pollution. However, the use of the position detection device of the utility model can ensure that the suction gun is in place and prevent the liquid in the tank from splashing out from the tank opening, because the shell 1 can cover the tank opening, and only the bottom 12 needs to be cleaned after use. A diaphragm pump can be set at the rear end of the position detection device. When the suction gun is inserted into the tank, the tank opening presses against the pressure plate 4, and then triggers the travel switch 3 to transmit a signal to the diaphragm pump at the rear end to start, so that the suction gun can be started as soon as it is inserted into place, which greatly improves work efficiency.
[0023] The pressing plate 4 is generally made of polytetrafluoroethylene, because the polytetrafluoroethylene has the properties of corrosion resistance, high temperature resistance, non-adhesion, etc., and can adapt to the working environment of various liquids.
