Description

Technical Field

[0001] The utility model relates to the field of electromagnetic water meters, in particular to a flow simulation tool for electromagnetic water meters. Background Art

[0002] Electromagnetic water meter is an intelligent water meter that uses Faraday's law of electromagnetic induction to achieve automatic metering. When water flows through the measuring device in the electromagnetic water meter, the charges in the conductor are deflected under the action of the magnetic field, generating an induced potential. The induced voltage signal is then read out by the sensor and processed to finally obtain an accurate flow value.

[0003] However, since the electromagnetic water meter needs liquid to be present inside the pipe to detect whether it can work normally, if the electromagnetic water meter cannot be used after installation, it is troublesome to disassemble and adjust it. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides an electromagnetic water meter flow simulation tooling to solve the problems mentioned in the above background.

[0005] The utility model provides the following technical solutions: an electromagnetic water meter flow simulation tooling, connected to the simulation tooling, including a detection water pipe arranged on the outside of the simulation tooling, the simulation tooling comprising: a main rod, a sliding sleeve rod, the main rod is provided with a slide groove inside, one end of the sliding sleeve rod is located inside the slide groove and is connected with a hook rod, the outside of the hook rod is located at the front and rear of the sliding sleeve rod and is equipped with scissor-type brackets, the upper and lower ends of the scissor-type bracket are equipped with contact pads, the outer end of the hook rod is located in front of the scissor-type bracket and is equipped with an elastic rubber strip, the front surface of the sliding sleeve rod is equipped with a resistor mounting seat, and the resistor mounting seat is equipped with a detection resistor.

[0006] As a further solution of the present invention: an electrical wire is connected between the detection resistor and the contact pad.

[0007] As a further solution of the utility model: a movable shaft is connected between the end of the scissor-type bracket away from the hook rod and the main rod, and a flow meter connector is installed on the outer side of the detection water pipe at a position corresponding to the contact pad.

[0008] As a further solution of the utility model: the scissor-type bracket is slidably connected to the slide groove through the hook rod, and the detection resistor is clamped with the resistor mounting seat.

[0009] As a further solution of the utility model: the flow meter connector is fixedly connected to the detection water pipe.

[0010] As a further solution of the utility model: a resistor cover is installed in front of the resistor mounting seat and on the outside of the detection resistor.

[0011] As a further solution of the utility model: a movable shaft is connected between the contact pad and the scissor-type bracket, and the sliding sleeve rod is slidably connected to the main rod.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] When the sliding sleeve rod moves as a whole, the control hook rod drives one end of the scissor-type bracket to move inside, and the upper end of the scissor-type bracket will control the contact pad as a whole to contact the flow meter joint on the inner wall of the detection water pipe through the connecting shaft. Then, the two flow meter joints as a whole will control the detection resistor and the electromagnetic water meter to generate an electrical path to complete the detection under the action of the electrical connecting line. At the same time, the overall longitudinal length of the scissor-type bracket can be adjusted to realize the connection detection of pipes with different diameters.

[0014] After connecting the electric meter to be tested on the outside of the test water pipe, the flow detection of the electromagnetic water meter can be carried out by placing a simulation tool inside the test water pipe. The detection purpose of the electromagnetic water meter can be completed when there is no liquid flowing in the water pipe. The pipeline does not need to be closed and the operation can be carried out in an open state, which facilitates the installation and disassembly of the simulation tool and improves the detection efficiency.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-4 As shown, this embodiment provides an electromagnetic water meter flow simulation tooling, connected to the simulation tooling 2, including a detection water pipe 1 arranged on the outside of the simulation tooling 2, and the simulation tooling 2 includes: a main rod 201, a sliding sleeve rod 202, the sliding sleeve rod 202 is slidably connected to the main rod 201, a slide groove 209 is opened inside the main rod 201, one end of the sliding sleeve rod 202 is located inside the slide groove 209 and is connected to a hook rod 208, a scissor bracket 203 is slidably connected to the slide groove 209 through the hook rod 208, and the outside of the hook rod 208 is located at the front and rear of the sliding sleeve rod 202, and the upper side of the scissor bracket 203 is installed. Contact pads 205 are installed at both ends of the lower part, and a movable shaft is connected between the contact pad 205 and the scissor-type bracket 203. The outer end of the hook rod 208 is located in front of the scissor-type bracket 203 and is installed with an elastic rubber strip 207. When the sliding sleeve 202 is controlled to slide as a whole inside the slide groove 209, the overall horizontal length of the scissor-type bracket 203 is reduced and the vertical length is increased, so the elastic rubber strip 207 is stretched and deformed vertically as a whole. A resistor mounting seat 204 is installed on the front surface of the sliding sleeve 202, and a detection resistor 206 is arranged inside the resistor mounting seat 204, and the detection resistor 206 is clamped with the resistor mounting seat 204.

[0022] like Figure 2-3 As shown, in the present embodiment, an electrical conductor is connected between the detection resistor 206 and the contact pad 205, a resistor cover is installed in front of the resistor mounting seat 204 and on the outside of the detection resistor 206, a movable axis is connected between the scissor-type bracket 203 and the main rod 201 at one end away from the hook rod 208, and a flow meter connector 3 is installed on the outside of the detection water pipe 1 at a position corresponding to the contact pad 205, and the flow meter connector 3 is fixedly connected to the detection water pipe 1.

[0023] The working principle of the utility model is as follows: when in use, the electromagnetic water meter is installed as a whole on the outside of the detection water pipe 1, and the flow meter connector 3 and the contact point of the electromagnetic water meter are connected, and the simulation tooling 2 is placed as a whole inside the detection water pipe 1. When performing simulated detection, a force is applied to the sliding sleeve rod 202 as a whole to simulate the flow direction of water. When the sliding sleeve rod 202 moves as a whole, the end of the sliding sleeve rod 202 controls the hook rod 208 as a whole to drive one end of the scissor-type bracket 203 to move inside the slide groove 209, and the scissor-type bracket 203 as a whole will be deformed, the lateral length of the scissor bracket 203 will be reduced, and the longitudinal length will be increased. Then, the upper end of the scissor-type bracket 203 will control the contact pad 205 as a whole to contact the flow meter connector 3 on the inner wall of the detection water pipe 1 upward through the connecting shaft. After that, the two flow meter connectors 3 as a whole will control the detection resistor 206 to generate an electrical path with the electromagnetic water meter under the action of the electrical connecting line, and then it can be realized to detect whether the electromagnetic water meter can work normally in the waterless opening state.
