下面结合图1至图5对本申请实施例提供的一种脉冲钻进装置进行描述。应当理解的是，以下所述仅是本申请的示意性实施方式，并不对本申请构成任何特别限定。
本申请的实施例提供了一种脉冲钻进装置，如图1、图2和图4所示，该脉冲钻进装置包括：多个钻杆100、钻头、储能电容300和放电开关400。
其中，各钻杆100上均对应连接有储能电容300。储能电容300能够为与其相连的钻杆100充电。钻头与钻杆100连接，放电开关400与钻杆100连接，以控制钻杆100放电至钻头并破碎岩石。并且，多个钻杆能够实现连续交替充电和放电。
与现有技术相比，该脉冲钻进装置设有多个钻杆100，各钻杆100均相应配置连接有储能电容300。放电开关400能够相应控制各钻杆100的充电状态。其中一个钻杆100处于放电状态时，其余钻杆100均处于充电状态。 处于放电状态的钻杆100的电能耗尽后转为充电状态，同时使得满电状态的钻杆100进行连续放电。由此，多个钻杆100能够实现连续交替充电和放电，进而极大提升了钻进效率。
例如，在本申请的一个实施例中，如图1所示，钻杆100包括第一钻杆101、第二钻杆102、第三钻杆103和第四钻杆104。第一钻杆101、第二钻杆102、第三钻杆103和第四钻杆104均相应地配置连接有储能电容300。假设放电开关400首先控制第一钻杆101放电至钻头进行破碎岩石，则第二钻杆102、第三钻杆103和第四钻杆104均处于充电状态。当第一钻杆101的电能耗尽时，放电开关400可以控制第二钻杆102、第三钻杆103和第四钻杆104中的任意一个钻杆100放电至钻头进行破碎岩石。同时，储能电容300为第一钻杆101进行充电。以此规律循环往复，由此，第一钻杆101、第二钻杆102、第三钻杆103和第四钻杆104能够实现连续交替充电和放电，进而极大提升了钻进效率。
此处应当说明的是，上述实施例仅是本申请的一个示意性实施例，并不能对本申请构成任何限定。钻杆100的数量可以根据实际需求自行确定。
例如，在本申请的一个实施例中，钻头包括一体式钻头201。各钻杆100均与一体式钻头201连接。
如图2和图3所示，该脉冲钻进装置包括一个一体式钻头201。多个钻杆100均与该一体式钻头201连接。任意钻杆100均可放电至该一体式钻头201进行破碎岩石。安装有一体式钻头201的脉冲钻进装置能够实现小直径同等能量条件下的持续钻进工作。
又例如，在本申请的一个实施例中，钻头包括多个分体式钻头202。各钻杆100上均配置连接有一个分体式钻头202。
如图4和图5所示，该脉冲钻进装置包括多个分体式钻头202。分体式钻头202的数量与钻杆100的数量相等。也就是说，每个钻杆100上均配置连接有分体式钻头202。各钻杆100能够放电至与其连接的相应的分体式钻头202上进行破碎岩石。安装有分体式钻头202的脉冲钻进装置能够实现小能量大直径的持续钻进工作。
在本申请的一个实施例中，钻头通过钻头连接件500与钻杆100可拆卸连接。
根据以上描述的实施例可知，通过更换钻头的种类，使得该脉冲钻进装置能够适用于不同工况下的持续钻进工作，极大提升了该脉冲钻进装置的灵活性和通用性。
在本申请的一个实施例中，每个钻杆100均相应配置有一个放电开关400，以控制各钻杆100的工作状态。
例如，第一钻杆101配置连接有第一放电开关。第二钻杆102配置连接有第二放电开关。第三钻杆103配置连接有第三放电开关。第四钻杆104配置连接有第四放电开关。当需要第一钻杆101进行放电时，第一放电开关处于导通状态，第一钻杆101放电至钻头进行破碎岩石。此时，第二放电开关、第三放电开关和第四放电开关均处于截止状态，第二钻杆102、第三钻杆103和第四钻杆104均处于充电状态。当第一钻杆101的电能耗尽时，使得第一放电开关、第三放电开关和第四放电开关处于截止状态，第二放电开关处于导通状态，第二钻杆102放电至钻头进行破碎岩石，其余钻杆均处于充电状态。
在本申请的一个实施例中，钻杆100与钻头连接件500的连接端口处的低压端与高压端之间设有绝缘层。绝缘层用于隔绝高压电极钻头与低压电极钻头及外壳连接，防止电能泄露，引起安全问题。
在本申请的一个实施例中，脉冲钻进装置还包括控制单元。控制单元与各放电开关400均电性连接，以通过控制各放电开关400的工作状态来控制各钻杆100的放电时间和放电顺序。
进一步，在本申请的一个实施例中，每个钻杆100上至少配置连接有一个储能电容300。各储能电容300均与高压电源连接。高压电源与控制单元电性连接。结合上述实施例具体来讲，该脉冲钻进装置还包括控制单元。控制单元与第一放电开关、第二放电开关、第三放电开关和第四放电开关均电性连接。每个钻杆100上均可以配置有多个储能电容300，各储能电容300均与高压电源连接。高压电源能够将常规220V市电或380V工业电转化为高压直流电，转储到储能电容300中以为第一钻杆101、第二钻杆102、第三钻杆103和第四钻杆104进行充电。控制***能够控制高压电源为第一钻杆101、第二钻杆102、第三钻杆103和第四钻杆104相对应的储能电容300充电。
同时，控制***还可以设定一定的放电时间和一定的放电顺序。例如， 控制***可以设定放电顺序依次为第一钻杆101、第二钻杆102、第三钻杆103和第四钻杆104。每个钻杆100的放电时间为30min。
开始时，控制***控制第一放电开关处于导通状态，第二放电开关、第三放电开关和第四放电开关均处于截止状态。此时，第一钻杆101放电至钻头进行破碎工作。同时，控制***控制高压电源为第二钻杆102、第三钻杆103和第四钻杆104进行充电。第一钻杆101放电30min后，控制***控制第一放电开关、第三放电开关和第四放电开关处于截止状态，第二放电开关处于导通状态。此时，第二钻杆102放电至钻头进行破碎工作。同时，控制***控制高压电源为第一钻杆101、第三钻杆103和第四钻杆104进行充电。第二钻杆102放电30min后，第一放电开关、第二放电开关和第四放电开关处于截止状态，第三放电开关处于导通状态。此时，第三钻杆103放电至钻头进行破碎工作。同时，控制***控制高压电源为第一钻杆101、第二钻杆102和第四钻杆104进行充电。第三钻杆103放电30min后，第一放电开关、第二放电开关和第三放电开关处于截止状态，第四放电开关处于导通状态。此时，第四钻杆104放电至钻头进行破碎工作。同时，控制***控制高压电源为第一钻杆101、第二钻杆102和第三钻杆103进行充电。由此规律，进行下一循环连续充电和放电工作。
此处应当理解的是，每根钻杆100上至少配置连接有一个储能电容300。每根钻杆100上所配置连接的储能电容300可以根据实际需求自行调整。所有储能电容可以与同一个高压电源连接。
在本申请的一个实施例中，脉冲钻进装置还包括壳体600。各储能电容300和各钻杆100均安装于壳体600内。
进一步，在本申请的一个实施例中，如图1至图5所示，壳体600内设有排渣通道700。多个钻杆100以排渣通道700的中心点为阵列中心点环形阵列在壳体600的内部。
如图1所示，排渣通道700位于多个钻杆100的中心位置。用于打压泥浆，冲出破碎岩石的碎渣，实现正循环排渣。或者从排渣通道700将碎渣吸出，实现反循环排渣。
根据以上描述的实施例可知，该脉冲钻进装置的结构简单、紧凑，易于操作。相较于传统机械破碎方式，其破碎效率大幅提升，且工作成本较低。 同时，该装置能够适用于不同工况下的钻进工作，具有较高的灵活性和通用性。另外，与现有的脉冲钻进装置相比较，该装置能够真正实现连续充电和连续放电，进而实现连续钻进工作，其钻进工作效率极大提升。
最后应说明的是：以上实施例仅用以说明本申请的技术方案，而非对其限制；尽管参照前述实施例对本申请进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例技术方案的精神和范围。
