All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As a specific implementation object of the present invention, the working shed for cable joints is mainly suitable for being laid in the cable trench 800 at a corresponding position where a cable joint needs to be made during a cable construction process. The air quality of the working area for improving the cable joint manufacturing and the working difficulty of building an operation shed in the working area are reduced.

The power cable is mainly used for power transmission, and is usually installed below the ground surface, and is laid in the cable trench 800 in a pipe arrangement or a tunnel. The tunnel depth is in 10 ~ 30 meters underground within a definite time, and the environment in the tunnel mainly has humidity big, the dust is serious, illumination is not enough three technical problem.

Referring to fig. 1, as an embodiment of the present invention, the working shed for cable joints includes an inflatable shed, an inflator 200, an air circulation device 400 and a controller, the inflator 200 inflates the inflatable shed so that the inflatable shed is supported above a cable trench 800, the inflatable shed and the cable trench 800 enclose a closed operating room 160, the air circulation device 400 is used for providing fresh air into the operating room 160, the air circulation device 400 is electrically connected with the controller, and the controller is used for controlling the working state of the air circulation device 400.

Further, the inflatable shelter body is a bottom-suspended enclosure surrounded by the top surface 110, the side walls 120, the front end surface 130 and the rear end surface 140. The top surface 110 and the side wall 120 are both composed of a plurality of inflatable columns 150 arranged side by side, and the gaps between the adjacent inflatable columns 150 are connected through a flexible film. The inflator 200 inflates the inflation column 150. The front and

rear faces

130, 140 are used to provide access openings 161 for personnel and equipment to access the operator cab 160.

Optionally, the plurality of columns are interconnected.

Optionally, the inflatable shed main body is made of a transparent flexible film, and comprises the inflatable columns 150 and the flexible film connected between the inflatable columns 150, so that the shielding of external light rays is reduced to the greatest extent.

Optionally, the middle portion of the top surface 110 is upwardly arched.

By adopting the environment treatment device provided by the utility model, manual support building and film laying are not needed on site, the inflatable shed can be supported above the cable trench 800 and forms a relatively closed operation chamber 160 with a certain supporting force by inflating through the inflator pump 200, the air circulation device 400 works to form air circulation in the operation chamber 160, a good air environment is provided in the inflatable shed, and the working efficiency of cable joint manufacturing can be greatly improved.

Correspondingly, the air circulation device 400 includes, but is not limited to, any one or more of a scrubber, a heater, a fan, a dehumidifier, and a regeneration air exchanger.

Based on practical experience, it is not difficult to know that the main factors causing poor environmental quality in the cable trench 800 are derived from the following aspects:

first, the humidity is high. Because the underground water system is abundant, the soil water content increases along with the tunnel degree of depth, and have the temperature difference with ground in the tunnel in addition, lead to when ground air and the interior air of tunnel pass through the working well and exchange, form the comdenstion water in the tunnel easily. Therefore, the humidity in the tunnel is high, and the air humidity is usually over 90%;

secondly, the dust is severe. The dust that leaves in the tunnel construction, the dust that brings into the tunnel during cable laying and the earth granule etc. that brings into when personnel pass in and out the tunnel often can pile up on the tunnel bottom surface, when opening the tunnel work well fan and carry out the tunnel ventilation time, the dust just blows off in the air. The result of field test of the concentration of suspended particles in the air is that 1.0 mu m is more than or equal to 35000 PC/liter.

From this, utilize air cycle device 400 to exert power in the control chamber 160 in order to form air cycle, be favorable to removing dust, temperature regulation and control, humidity regulation and control to the air in the control chamber 160, can be in order to guarantee the clean pollution-free of the cable joint of preparation, prolong cable joint's life can provide a more comfortable air circumstance again for the constructor, reduce the infringement of dust air to constructor's healthy.

Optionally, the inflatable column 150 is further provided with an air hole 151, the inflator 200 continuously inflates the inflatable column 150, and excess air in the inflatable column 150 is discharged from the air hole 151, so that the air pressure in the inflatable column 150 is balanced.

Optionally, the air hole 151 faces the operation chamber 160. The surplus air in the air column 150 is used to provide a small amount of air flow to the operation chamber 160, so that the whole equipment can be operated under the condition that the air circulation device 400 does not work, and the use requirement is met.

Optionally, a dust-removing filter 300 is disposed at an air inlet of the inflatable pillar 150, and the dust-removing filter 300 is used to prevent dust in the air from entering the inflatable pillar 150, and further prevent the dust from entering the operation chamber 160 through the air hole 151.

In order to eliminate the above-mentioned problems of air humidity and dust, there is a problem that the illumination is generally poor in the cable pit 800. The existing device replaces a single-layer film or an inflatable shed to seal a joint area, a temporary construction illuminating lamp is connected in the joint shed, due to the fact that an operation shed is limited to the shielding of natural light and the lighting condition of a construction site, the illumination is angled and only local illumination is achieved, the inside of the operation shed cannot provide an even and sufficient illumination environment, the vision is limited in the process of manufacturing a cable joint, certain negative effects are caused on operation procedures, the connection quality of cables cannot be guaranteed in the environment, the reworking of the cable joint is caused, the construction period is delayed, and economic loss can be caused.

Therefore, the working shed for cable connectors provided by the utility model further comprises a lighting device for providing uniform illumination for the inside of the operation room 160, wherein the lighting device is electrically connected with the controller, and the working state of the lighting device is controlled by the controller.

Optionally, the lighting device includes a plurality of LED lighting patches 500, the LED lighting patches 500 being uniformly disposed on the interior surface of the inflatable shed. The LED light emitting patch 500 is cold light emitting, not by heating or discharging light emitting, has the advantages of long service life, fast lighting response speed, high electro-optical conversion efficiency, low power consumption, good shock resistance, high reliability, easy light weight, and no shape limitation, and is easily manufactured into various applications and different use occasions.

Optionally, an environment monitoring device 600 is disposed in the operation room 160, and is configured to monitor the air quality in the operation room 160 and perform visual display through an instrument panel or a display device, so as to facilitate obtaining the environmental parameters in the operation room 160 more intuitively.

Optionally, the air circulation device further comprises an alarm device 700, the alarm device 700 is electrically connected to the environment monitoring device 600, and the alarm device 700 receives the monitoring signal from the environment monitoring device 600 and gives an alarm according to the monitoring signal, so as to operate the air circulation device 400 in time to regulate and control the air environment in the operation room 160.
