矿井是形成地下煤矿生产系统的井巷、硐室、装备、地面建筑物和构筑物的总称。有时把矿山地下开拓中的斜井、竖井、平硐等也称为矿井。每一个矿井的井田范围大小、矿井生产能力和服务年限的确定,是矿井自体设计中必须解决好的关键问题之一,废弃矿井需要对其进行规范封存避免其产生安全隐患。A mine is a general term for the shafts, chambers, equipment, ground buildings and structures that form an underground coal mine production system. Sometimes, the inclined shafts, vertical shafts, and horizontal shafts in the underground development of mines are also called mines. The size of the mine field, the production capacity and service life of each mine are one of the key issues that must be solved in the mine design. Abandoned mines need to be sealed in a standardized manner to avoid potential safety hazards.

为解决废弃矿井需要对其进行规范封存避免其产生安全隐患的问题,市场中的深地封存井的井口采用架设防护井盖的设计,具有一定的市场占比。In order to solve the problem of abandoned mines needing to be sealed in a standardized manner to avoid potential safety hazards, the wellheads of deep underground sealed wells in the market are designed with protective manhole covers, which have a certain market share.

现有深地封存井的井口常年带有压力,因此压力一股涌上会出现防护井盖被冲破的风险性,因此需要设计一种具有压力分散机构的深地封存井的井口保护装置来解决以上问题。The wellheads of existing deep sealed wells are under pressure all year round, so there is a risk that the protective well cover will be broken when the pressure surges. Therefore, it is necessary to design a wellhead protection device for deep sealed wells with a pressure dispersion mechanism to solve the above problem.

具体实施方式DETAILED DESCRIPTION

下面结合附图对本申请的两种实施方式作详细说明。Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

第一种实施方式:The first implementation method:

图2-3示出包括安装在井体7上端的井盖3,井盖3的上端安装有密封箱1,密封箱1的下端安装有第一自转轴6,第一自转轴6的下端安装有第二自转轴8,井盖3的下端固定连接有弧形导气面4,弧形导气面4延伸至密封箱1内,第一自转轴6贯穿弧形导气面4,第一自转轴6的外端固定连接有扇叶5,第二自转轴8的外端对称固定连接有多个柔性飘带9。Figure 2-3 shows a manhole cover 3 installed at the upper end of a well body 7, a sealing box 1 is installed at the upper end of the manhole cover 3, a first rotating shaft 6 is installed at the lower end of the sealing box 1, a second rotating shaft 8 is installed at the lower end of the first rotating shaft 6, a curved air guide surface 4 is fixedly connected to the lower end of the manhole cover 3, the curved air guide surface 4 extends into the sealing box 1, the first rotating shaft 6 passes through the curved air guide surface 4, a fan blade 5 is fixedly connected to the outer end of the first rotating shaft 6, and a plurality of flexible streamers 9 are symmetrically fixedly connected to the outer end of the second rotating shaft 8.

图1-3示出密封箱1的内端固定连接有电机2,电机2的输出端与第一自转轴6相连接,密封箱1的前端固定连接有警示牌13,井盖3的上端对称开设有开孔14,第一自转轴6和第二自转轴8之间安装有轴承件10。Figure 1-3 shows that the inner end of the sealing box 1 is fixedly connected to the motor 2, the output end of the motor 2 is connected to the first rotating shaft 6, the front end of the sealing box 1 is fixedly connected to the warning sign 13, the upper end of the manhole cover 3 is symmetrically provided with openings 14, and a bearing 10 is installed between the first rotating shaft 6 and the second rotating shaft 8.

图1-3示出本方案通过在井体7上设置井盖3起到防护作用,并且在井体7内延伸第一自转轴6利用电机2驱动扇叶5转动令井体7口部气压均匀分布,并在第一自转轴6下延伸更深长度的第二自转轴8,第二自转轴8外的柔性飘带9跟随第二自转轴8的转动而飘动,令井体7内气压呈稳定状逐步上升,上升的气压通过弧形导气面4的斜坡面稳定的输送至井盖3两侧的开孔14中散出井体7外,进而避免井体7中的局部气压聚集而导致井体7发生危险的风险性,利于保障井体7的安全性,同时在密封箱1前可设置警示牌13,用于起到警示作用,避免闲杂人员靠近井体7。Figures 1-3 show that the present solution plays a protective role by setting a manhole cover 3 on the well body 7, and extending a first rotating shaft 6 in the well body 7 to use a motor 2 to drive the fan blades 5 to rotate so that the air pressure at the mouth of the well body 7 is evenly distributed, and a second rotating shaft 8 of a deeper length is extended under the first rotating shaft 6. The flexible streamer 9 outside the second rotating shaft 8 floats along with the rotation of the second rotating shaft 8, so that the air pressure in the well body 7 is stable and gradually rises. The rising air pressure is stably transported to the openings 14 on both sides of the manhole cover 3 through the slope surface of the arc-shaped air guide surface 4 and dispersed out of the well body 7, thereby avoiding the risk of local air pressure accumulation in the well body 7 causing danger to the well body 7, which is beneficial to ensuring the safety of the well body 7.

The end of the transverse clamping plate 11 away from the bearing member 10 is fixedly connected with an inclined clamping surface 12, and the inclined clamping surface 12 abuts against the inner wall of the well body 7. At the same time, a rotatable transverse clamping plate 11 can be arranged between the first rotation axis 6 and the second rotation axis 8. When the first rotation axis 6 and the second rotation axis 8 are placed into the well body 7, the two transverse clamping plates 11 fall down until the inclined clamping surface 12 abuts against the inner wall of the well body 7, thereby ensuring the stability of the rotation path of the first rotation axis 6 and the second rotation axis 8, and thus ensuring their operating efficiency.
