Description

Technical Field

[0001] This utility model relates to the field of level gauges, and in particular to protective level gauges. Background Technology

[0002] The working principle of a level gauge is as follows: when the liquid level in the measured container rises or falls, the float in the main control tube of the level gauge also rises or falls accordingly. The permanent magnet inside the float transmits the signal to the local indicator via magnetic coupling, driving the red and white indicator columns to rotate 180°. When the liquid level rises, the indicator column changes from white to red; when the liquid level falls, the indicator column turns back to white. The red and white interface on the indicator shows the actual height of the medium in the container, thus indicating the liquid level. However, existing level gauges lack protection on the gauge head, making them prone to breakage due to external forces, and the gauge head height cannot be adjusted. Utility Model Content

[0003] In order to overcome the shortcomings of existing level gauges that lack protection and cannot adjust the height, this utility model provides a protective level gauge.

The gauge head is installed at the top of the probe rod, and the float is movably connected to the probe rod. A flange is fixed on the probe rod, and a protective cover is detachably installed on the flange. The gauge head is slidably connected to the flange, and a lifting mechanism is installed on the protective cover. The lifting mechanism is connected to the gauge head, and the gauge head is slidably connected to the probe rod.

The threaded rod is rotatably connected to the protective cover, and the threaded rod and the nut are threaded together. The nut is fixedly connected to the meter head through the connecting frame.

[0006] According to another embodiment of the present invention, the threaded rod is further provided with a handle at its top end.

[0007] According to another embodiment of the present invention, the outer tube is fixed to the bottom of the meter head, and the inner tube is fixed to the flange, with the outer tube and the inner tube being slidably connected together.

[0008] According to another embodiment of the present invention, the instrument head is further provided with a slide rod fixed at the bottom, one end of the slide rod being slidably connected to the inner cavity of the probe rod, and the slide rod being located inside the outer tube and the inner tube.

[0009] According to another embodiment of the present invention, the protective cover is further provided with a light-shielding layer.

[0010] According to another embodiment of the present invention, the protective cover is further provided with an opening on the front end plate, and an inspection door is hinged at the opening.

[0011] According to another embodiment of the present invention, the protective cover is further comprising a transparent cover.

[0012] The beneficial effects of this utility model are that it protects the meter head and the connection between the meter head and the flange through a protective cover. The height of the meter head is adjusted through a lifting mechanism. Attached Figure Description

[0015] Figure 1 This is a schematic diagram of the structure of this utility model.

[0016] As attached Figure 1 As shown, a protective level gauge includes a gauge head 1, a probe rod 2, and a float 3. The gauge head 1 is installed at the top of the probe rod 2, and the float 3 is movably connected to the probe rod 2. A flange 4 is fixed to the probe rod 2, and a protective cover 5 is detachably installed on the flange 4. The gauge head 1 is slidably connected to the flange 4, and a lifting mechanism 6 is installed on the protective cover 5. The lifting mechanism 6 is connected to the gauge head 1, and the gauge head 1 is slidably connected to the probe rod 2.

[0017] The protective cover 5, together with the flange 4, forms a closed space, and the gauge head 1 and the mechanism between the gauge head 1 and the flange 4 are placed within this closed space, thus providing protection.

[0018] The lifting mechanism 6 includes a threaded rod 61, a nut 62, and a connecting frame 63. The threaded rod 61 is rotatably connected to the protective cover 5. The threaded rod 61 and the nut 62 are threaded together. The nut 62 is fixedly connected to the meter head 1 through the connecting frame 63.

[0019] The threaded rod 61 has a handle at its top.

[0020] The operator can rotate the threaded rod 61 by holding the handle, which will drive the nut 62 to move up and down along the threaded rod 61, so that the threaded rod 61 drives the gauge head 1 to move up and down, thereby achieving the purpose of adjusting the height of the gauge head 1.

[0021] An outer tube 7 is fixed at the bottom of the gauge head 1, and an inner tube 8 is fixed on the flange 4. The outer tube 7 and the inner tube 8 are slidably connected together.

[0022] When the meter head 1 moves up and down, the outer tube 7 and the inner tube 8 will move relative to each other, thus ensuring the stability of the movement of the meter head 1.

[0023] A slide rod 9 is fixed to the bottom of the meter head 1. One end of the slide rod 9 is slidably connected to the inner cavity of the probe rod 2. The slide rod 9 is located inside the outer tube 7 and the inner tube 8. The slide rod 9 will move vertically up and down along the inner tube 8.

[0024] The protective cover 5 is equipped with a light-shielding layer.

[0025] The front end plate of the protective cover 5 has an opening, and an inspection door 10 is hinged to the opening. The swinging inspection door 10 can open and close the opening.

[0026] Protective cover 5 is a transparent cover.
