Description

Technical Field

[0001] The utility model belongs to the field of electrical cabinets, and particularly relates to an ozone gathering device for a distribution cabinet. Background Art

[0002] If the bolts in the distribution cabinet are loose, arcing is likely to occur, which can damage electrical components. Arcing will produce ozone. The common practice in the prior art is to monitor whether the distribution cabinet is discharging by monitoring the ozone content (for example, a self-powered ozone monitoring sensor and signal processing method for a distribution cabinet disclosed in Chinese patent document CN115718175A). Ozone monitoring mainly relies on ozone sensors, but due to the relatively low ozone content, the accuracy of monitoring mainly depends on the sensitivity of the sensor itself (for example, the ozone concentration sensor mentioned in Chinese patent document CN214204410U). The monitoring effect is not ideal, and it cannot respond in time when arcing occurs. Therefore, it is necessary to design an ozone gathering device to gather air together and improve the sensitivity of monitoring. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide an ozone gathering device for a distribution cabinet, which can concentrate the air from different directions and positions into the chamber of a gas gathering shell. The gas gathering shell is used to install an ozone concentration sensor. The probability of the ozone concentration sensor detecting ozone will be greatly increased, thereby improving the detection accuracy.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0005] An ozone gathering device for a power distribution cabinet comprises a gas gathering shell, wherein the outer wall of the gas gathering shell is provided with a plurality of hoses, one end of the hoses is a collection port, and the other end of the hoses is connected to a chamber of the gas gathering shell; a detachable fixing is installed at the collection port of the hose, and the detachable fixing is used to be fixed to the inner wall of the power distribution cabinet; the middle part of the gas gathering shell is connected to an insert tube, and the insert tube is detachably connected to an exhaust fan.

[0006] Preferably, the detachable fixing member comprises a clamp, and a magnet is mounted on the outer wall of the clamp.

[0007] Preferably, the hose is a threaded telescopic hose.

[0008] Preferably, the insert tube is used to be installed on the installation hole of the power distribution cabinet, and the insert tube is connected to the exhaust fan by threads.

[0009] Preferably, a plurality of ozone concentration sensors are installed in the gas gathering shell, and the ozone concentration sensors are installed at the connection between the hose and the gas gathering shell.

[0010] The utility model can achieve the following beneficial effects:

[0011] The device can concentrate air from different directions and positions into the chamber of the gas gathering shell. The gas gathering shell is used to install an ozone concentration sensor. The probability of the ozone concentration sensor detecting ozone will be greatly increased, thereby improving the detection accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 This is the front view of the utility model;

[0014] Figure 2 It is a side view of the utility model;

[0015] Figure 3 This is a diagram showing the use of the utility model.

[0016] In the figure: a gas gathering shell 1, a hose 2, an insert tube 3, an exhaust fan 4, a detachable fixing part 5, a clamp 501, a magnet 502, and a distribution cabinet 6. DETAILED DESCRIPTION

[0017] The preferred solution is Figures 1 to 3 As shown, an ozone gathering device for a distribution cabinet comprises a gas gathering shell 1, the outer wall of which is provided with a plurality of hoses 2, one end of the hoses 2 being a collection port, and the other end of the hoses 2 being connected to the chamber of the gas gathering shell 1; a detachable fixing part 5 is installed at the collection port of the hose 2, and the detachable fixing part 5 is used to be fixed to the inner wall of the distribution cabinet; the middle part of the gas gathering shell 1 is connected with the insert tube 3, and the insert tube 3 is detachably connected with the exhaust fan 4.

[0018] Specifically, the insert tube 3 is used to be installed on the installation hole of the power distribution cabinet, and the insert tube 3 is threadedly connected to the exhaust fan 4. The entire device is installed on the side wall of the power distribution cabinet, and the collection port of the hose 2 is used to be arranged at multiple positions of the power distribution cabinet and fixed to the inner wall of the power distribution cabinet with a detachable fixing 5.

[0019] The detachable fixing member 5 comprises a clamp 501, and a magnet 502 is installed on the outer wall of the clamp 501. The clamp 501 is connected to the hose 2, and the magnet 502 is used to be adsorbed on the inner wall of the distribution cabinet. The purpose of using the magnet 502 is to facilitate the position of the collection port to be adjusted at any time.

[0020] Furthermore, the hose 2 is a threaded telescopic hose, which is convenient for adjusting its length.

[0021] Furthermore, a plurality of ozone concentration sensors are installed in the gas gathering shell 1, and the ozone concentration sensors are installed at the connection between the hose 2 and the gas gathering shell 1. The ozone concentration sensor is used to detect the ozone content. Compared with the traditional detection scheme, the present invention can suck the gas in the distribution cabinet space into the gas gathering shell 1. If there is ozone in the distribution cabinet, the ozone can be monitored in time.

[0022] In addition, a plurality of ozone concentration sensors are installed in the gas gathering shell 1. If a single ozone concentration sensor detects ozone first, it proves that an arc phenomenon has occurred in the component at the location of the collection port.

[0023] The above embodiments are only preferred technical solutions of the present invention and should not be regarded as limitations of the present invention. The protection scope of the present invention shall be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
