Description

Technical Field

[0001] The utility model relates to the technical field of voltage regulating and metering cabinets, in particular to a voltage regulating and metering cabinet. Background Art

[0002] The gas pressure regulating and metering cabinet is a device that adjusts the gas pressure and maintains stability. The pressure regulating device is placed in a special box, which is located near the building. It is responsible for regulating the gas pressure. The basic function of the pressure regulating box is to reduce the higher pressure gas to the pressure required by the user and maintain stability. The working principle of the pressure regulator is that the gas enters the pressure regulating chamber from the inlet. When the valve port is opened, the gas enters the pressure reduction stage through the valve port, and the gas pressure is controlled within the range required by the user. When there is a problem with the gas pressure regulating and metering cabinet, the internal pipeline needs to be inspected and repaired.

[0003] The Chinese patent publication number: CN211954215U discloses a gas pressure regulating metering cabinet. The application states: "Metering cabinets in the prior art are mostly installed outdoors, but they do not have a certain anti-collision ability and will fall down when impacted; they cannot effectively prevent dust from entering the cabinet while dissipating heat; they do not have any drying function, and in continuous rainy weather, the cabinet is overly humid, thereby affecting the internal metering instruments or meters." Although the application solves this problem, it has the following defects:

[0004] The gas pressure regulating and metering cabinet provided in the above-mentioned prior art is an integral setting, and the size of the cabinet door is limited. When it is necessary to inspect the internal pipeline, the operation is extremely inconvenient, which greatly reduces the inspection efficiency. In addition, when a gas leak occurs, it is impossible to detect and alarm in time, which easily causes the expansion of safety accidents. For this reason, we propose a pressure regulating and metering cabinet. Utility Model Content

[0024] The embodiments of the present utility model will be further described below in conjunction with the accompanying drawings.

[0025] Example:

[0026] like Figure 1-Figure 5 As shown, a voltage regulating and metering cabinet includes a base 1, a lower shell 6 is fixedly connected to the top of the base 1, an upper shell 4 is arranged above the lower shell 6, a monitoring component 3 is fixedly connected to the top of the upper shell 4, a maintenance mechanism 2 is fixedly connected to the outer side of the lower shell 6, and a door panel 5 is hinged on the front side of the lower shell 6 through a hinge.

[0027] The maintenance mechanism 2 includes a cover body 202, which is fixedly connected to the left side of the lower shell body 6. The front and rear sides of the cover body 202 are movably connected to the same threaded rod 207 through bearings. The left side of the upper shell body 4 is fixedly connected to an L-shaped bar 201, the right side of the upper shell body 4 is fixedly connected to an L-shaped block 208, the top of the lower shell body 6 is provided with a rail groove 211, and the bottom of the upper shell body 4 is fixedly connected to a slide rail 212.

[0028] The working principle of the above technical solution is as follows:

[0029] When the gas pipeline in the lower shell 6 needs to be inspected, the rotating block 204 is rotated. The rotation of the rotating block 204 drives the threaded rod 207 to rotate. The rotation of the threaded rod 207 drives the L-shaped bar 201 to move backward. The backward movement of the L-shaped bar 201 drives the upper shell 4 to move backward until it stops moving. At this time, the pipeline inside the lower shell 6 can be inspected. After the inspection is completed, the threaded rod 207 is rotated in the opposite direction until the upper shell 4 is reset and stops.

[0030] In another embodiment, if Figure 3 As shown, a movable groove 203 is opened on the top of the cover body 202, the bottom of the L-shaped strip 201 passes through the movable groove 203 and extends into the cover body 202, the L-shaped strip 201 is threadedly connected to the outside of the threaded rod 207, the front end of the threaded rod 207 passes through the front side of the cover body 202, and the front end of the threaded rod 207 is fixedly connected to a rotating block 204.

[0031] The L-shaped bar 201 can be moved inside the movable groove 203 , and the upper shell 4 can be driven to move when the L-shaped bar 201 moves, thereby facilitating subsequent maintenance.

[0033] Under the action of the slider 205 and the slide groove 206 , the moving track of the L-shaped bar 201 can be limited to ensure that it can only move in the front-back direction.

[0034] In another embodiment, if Figure 5 As shown, a through hole is opened on the front side of the L-shaped block 208, and a slide rod 210 is slidably connected to the inside of the through hole. The front and rear ends of the slide rod 210 are fixedly connected to support blocks 209, and the support block 209 is fixedly connected to the right side of the lower shell 6.

[0035] The movement track of the L-shaped block 208 is limited by the action of the slide rod 210 and the through hole, thereby limiting the movement track of the upper shell 4 , and the slide rod 210 can be supported by the action of the support block 209 .

[0036] In another embodiment, if Figure 4 As shown, the monitoring component 3 includes a box body 302, which is fixedly connected to the top of the upper shell 4, a bell 304 is arranged on the inner side of the box body 302, a motor 306 is fixedly connected to the bottom of the box body 302, the motor 306 is fixedly connected to the cam 307 through the output shaft, a controller is fixedly connected to the front side of the box body 302, the output end of the controller is electrically connected to the motor 306 and the gas sensor 301, and the gas sensor 301 is fixedly connected to the top of the upper shell 4.

[0037] The motor 306 rotates to drive the cam 307 to rotate, and the cam 307 rotates to knock the bell pendant 305, and the bell pendant 305 moves to knock the inside of the bell 304, thereby generating a sound to alarm for gas leakage.

[0038] In another embodiment, if Figure 4 As shown, a hanging ring 303 is fixedly connected to the top of the box body 302 , and a bell 304 is movably connected to the inner side of the hanging ring 303 .

[0039] The bell 304 can be fixed under the action of the hanging ring 303, and the bell 304 can be shaken under the action of the hanging ring 303, so as to produce a sound when struck.

[0040] In another embodiment, if Figure 4 As shown, a protective net 308 is provided on both sides of the box body 302, and a bell pendant 305 is movably connected to the inner side of the bell 304.

[0041] The protection net 308 can facilitate the transmission of the sound, and the bell 304 can be struck by the bell pendant 305.

[0042] The above embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
