Description

Technical Field

[0001] This invention relates to the field of pyrotechnic detonation control technology, and in particular to an underwater electronic detonator detonation control device and detonation control method. Background Technology

[0002] Currently, electronic detonators are widely used in tunnel excavation, hazard removal blasting, demolition blasting, rock and ore separation, open-pit mine blasting, underwater blasting projects, and other applications. During detonation, the electronic detonator and the clamp are connected via connecting leads. The clamp is connected to the control bus, which in turn is connected to the detonation controller. The detonation controller transmits the detonation signal to the control circuit board of the electronic detonator via the control bus and connecting leads. The delay control chip in the electronic detonator presets the delay time, and the control circuit board issues a detonation command according to the preset delay time, thereby controlling the detonation of multiple electronic detonators.

[0003] However, when electronic detonators are used in underwater blasting operations, the low waterproof performance of the clamps increases the risk of water ingress, leading to leakage and short circuits as the clamps remain submerged in water for longer periods. This can cause some electronic detonators to fail to detonate properly. Furthermore, when the clamps are placed in water, the connecting wires can easily detach from the clamps due to water flow and waves, resulting in misfires and affecting the quality and reliability of underwater blasting.

[0004] Furthermore, when controlling the detonation of electronic detonators deployed underwater, it is often necessary to float the detonation controller in the water. In order to achieve this, the existing technology connects the detonation controller to a floating body. However, under the influence of water flow and waves, the detonation controller is easily wetted by the waves or even submerged, affecting its stability. Therefore, there is an urgent need for a detonation control device that can improve the reliability of underwater blasting. Summary of the Invention

[0005] The purpose of this invention is to overcome at least one deficiency of the prior art and provide an underwater electronic detonator initiation control device that is beneficial to improving the reliability of underwater blasting. In addition, an underwater electronic detonator initiation control method is also provided.

[0006] The technical solution of the present invention to solve the above-mentioned technical problems is as follows:

[0007] According to one aspect of this application, an underwater electronic detonator detonation control device is provided, comprising:

[0008] The lower half shell has a hollow cavity formed inside it. The upper opening of the hollow cavity forms an open end. The outer wall of the open end is connected to an annular protrusion.

[0009] The upper shell has a hollow cavity two inside, and the lower side of the hollow cavity two is open to form an open end two. The outer wall of the open end two is connected to an annular protrusion two. The upper shell covers the upper side of the lower shell. The annular protrusion two is set directly opposite the annular protrusion one, and the hollow cavity two is connected to the hollow cavity one to form an installation cavity.

[0010] An initiation control unit is disposed in the mounting cavity. The initiation control unit is used to communicate with the electronic detonator and to control the initiation of the electronic detonator that is communicated with it.

[0011] A sealing assembly is installed between the first annular protrusion and the second annular protrusion;

[0012] A locking mechanism is connected between the lower half-shell and the upper half-shell. The locking mechanism can lock the upper half-shell and the lower half-shell together, so that the sealing assembly seals the gap between the first annular protrusion and the second annular protrusion, forming a sealed space in the mounting cavity.

[0013] The beneficial effects of the present invention are as follows: In this embodiment, the outer wall of the open end one on the lower half shell is connected to an annular protrusion one, and the outer wall of the open end two on the upper half shell is connected to an annular protrusion two. A sealing component is installed between the annular protrusion one and the annular protrusion two, and the locking mechanism can lock the upper half shell and the lower half shell together, so that the sealing component seals the gap between the annular protrusion one and the annular protrusion two, forming a sealed space in the installation cavity. Therefore, when the underwater electronic detonator detonation control device in this embodiment is arranged in water for detonation control of the underwater electronic detonator, the detonation control unit is installed in the installation cavity, which avoids the detonation control unit from being wetted by the surging waves and also prevents the detonation control unit from being submerged in water, thereby improving the reliability of the underwater electronic detonator detonation control device for underwater blasting. Furthermore, in this embodiment, the upper half shell and the lower half shell are locked together by a locking mechanism. After the detonation control unit is arranged in the mounting cavity, the upper half shell and the lower half shell can be locked together by the locking mechanism, so that the sealing assembly seals the gap between the annular protrusion one and the annular protrusion two, which facilitates the arrangement of the detonation control unit and helps to ensure the reliability of the detonation control unit's waterproofing.

[0014] In addition, based on the above technical solution, the present invention can be further improved as follows, and can also have the following additional technical features.

[0015] According to one embodiment of this application, the underwater electronic detonator detonation control device further includes:

[0016] The connecting leads are provided with multiple leads spaced apart circumferentially, and one end of each connecting lead is electrically connected to the detonation control unit;

[0017] A waterproof isolation cover is installed between the first open end and the second open end. The waterproof isolation cover includes a cover body, an inner annular baffle, an inclined connecting ring, and an outer annular baffle. The inner annular baffle is connected to the periphery of the cover body and extends outward. One end of the inclined connecting ring is connected to the inner annular baffle. The cover body, the inner annular baffle, and the inclined connecting ring are located within the mounting cavity. The outer annular baffle is connected to the other end of the inclined connecting ring and is installed between the first annular protrusion and the second annular protrusion.

[0018] The sealing assembly includes:

[0019] An annular elastic sealing ring is installed between the annular protrusion and the outer annular baffle, and the annular elastic sealing ring elastically squeezes and seals the gap between the annular protrusion and the outer annular baffle.

[0020] A second annular elastic sealing ring is installed between the second annular protrusion and the outer annular baffle. The second annular elastic sealing ring elastically squeezes and seals the gap between the second annular protrusion and the outer annular baffle. The other end of each connecting leg extends out of the second annular elastic sealing ring and outwards.

[0021] In this embodiment, the connection point between one end of the connecting lead and the detonation control unit is located inside the mounting cavity, preventing the connection point from being submerged in water and improving the stability and reliability of the electrical connection between the connecting lead and the detonation control unit. Furthermore, in this embodiment, a waterproof isolation cover is installed between the first and second open ends. This waterproof isolation cover divides the mounting cavity into an upper and lower part, facilitating the arrangement of electronic components or other parts in the upper and lower parts respectively, reducing mutual interference between these components. Furthermore, annular elastic sealing ring one elastically compresses and seals the gap between annular protrusion one and the outer annular baffle, and annular elastic sealing ring two elastically compresses and seals the gap between annular protrusion two and the outer annular baffle, improving the reliability of the seal between the lower and upper shells. Additionally, the connecting lead extends through annular elastic sealing ring two, facilitating the arrangement of the connecting lead.

[0022] According to one embodiment of this application, the second annular elastic sealing ring includes:

[0023] The first annular elastic sealing ring 2 is installed on the upper side of the outer annular baffle;

[0024] The second annular elastic sealing ring is installed on the lower side of the second annular protrusion, opposite the first annular elastic sealing ring, and elastically pressed against the first annular elastic sealing ring. Each connecting lead passes through the first annular elastic sealing ring and the second annular elastic sealing ring. The first annular elastic sealing ring and the second annular elastic sealing ring elastically press and seal the gap between the first annular elastic sealing ring and the second annular elastic sealing ring. The first annular elastic sealing ring and the second annular elastic sealing ring elastically press and seal the gap between each connecting lead and the first annular elastic sealing ring and the second annular elastic sealing ring, respectively.

[0025] In this embodiment, the second annular elastic sealing ring includes a first annular elastic sealing ring and a second annular elastic sealing ring. Each connecting lead passes through the first annular elastic sealing ring and the second annular elastic sealing ring, which facilitates the flexible arrangement of multiple connecting leads and can adapt to the needs of arranging different numbers of connecting leads.

[0026] According to one embodiment of this application, the underwater electronic detonator detonation control device further includes:

[0027] An elastic wire-clamping ring is installed on the outer periphery of the inclined connecting ring. Multiple wire-clamping slots are circumferentially spaced on the outer wall of the elastic wire-clamping ring, corresponding to each of the connecting leads. The connecting leads are respectively clamped into the wire-clamping slots. The inner wall of the elastic wire-clamping ring elastically compresses the outer wall of the inclined connecting ring, elastically compressing and sealing the gap between the inner wall of the elastic wire-clamping ring and the outer wall of the inclined connecting ring. The outer wall of the elastic wire-clamping ring also elastically compresses the inner wall of the upper housing, elastically compressing and sealing the gap between the outer wall of the elastic wire-clamping ring and the inner wall of the upper housing. Furthermore, the inner wall of the wire-clamping slot compresses the connecting leads located within the wire-clamping slot, elastically compressing and sealing the gap between the inner wall of the wire-clamping slot and the outer wall of the connecting lead.

[0028] In this embodiment, an elastic retaining ring is installed on the outer periphery of the inclined connecting ring, which facilitates the locking of the connecting lead into the retaining groove, thereby limiting the position of the connecting lead. It also helps to compress the connecting lead through the elastic deformation of the elastic retaining ring, thereby fixing the connecting lead. Furthermore, the inner wall of the elastic retaining ring elastically compresses the outer wall of the inclined connecting ring, and the outer wall of the elastic retaining ring elastically compresses the inner wall of the upper shell, so that a second seal is formed between the elastic retaining ring and the inner wall of the inclined connecting ring and the upper shell, preventing water from seeping into the installation cavity along the connecting lead.

[0029] According to one embodiment of this application, a stop-top protrusion is provided on the inner sidewall of the upper housing opposite the inner annular baffle. The stop-top protrusion protrudes horizontally toward the inner side of the hollow cavity and is located above the inner annular baffle. The sealing assembly further includes:

[0030] An annular elastic sealing ring three is installed between the inner annular baffle and the stop protrusion. The inner annular baffle and the stop protrusion compress the annular elastic sealing ring three, causing the annular elastic sealing ring three to undergo elastic deformation and elastically compress and seal the gap between the inner annular baffle and the stop protrusion. The connecting lead passes through the annular elastic sealing ring three.

[0031] In this embodiment, an annular elastic sealing ring three is installed between the inner annular baffle and the stop protrusion. The annular elastic sealing ring three generates elastic deformation and elastically squeezes and seals the gap between the inner annular baffle and the stop protrusion, forming a third seal, which further prevents water from entering the installation cavity.

[0032] According to one embodiment of this application, the inner side of the cover forms a placement cavity with an open upper end, and the detonation control unit is installed inside the hollow cavity; the underwater electronic detonator detonation control device further includes:

[0033] Multiple wire clips are provided, each corresponding to one of the multiple connecting leads. One end of each connecting lead extends into the hollow cavity two. The end of each connecting lead extending into the hollow cavity two is connected to one of the wire clips and is electrically connected. Multiple wire clips are placed in the placement cavity.

[0034] Waterproof aviation plug 1 is installed on the cover. One end of the waterproof aviation plug 1 extends out of the cover and into the hollow cavity 1 to form a conductive connection end 1. The other end of the waterproof aviation plug 1 extends into the placement cavity to form a conductive connection end 2.

[0035] Control bus one, one end of which is electrically connected to the detonation control unit, and the other end of which is electrically connected to the conductive connection terminal one;

[0036] Control bus II, one end of which is electrically connected to conductive connection terminal II, and multiple clamps are respectively connected to the other end of control bus II and electrically connected to control bus II.

[0037] In this embodiment, the connecting leads are electrically connected to the detonation control unit via wire clamps. This facilitates operation and reduces the difficulty and workload of connecting the connecting leads to the detonation control unit. It also allows for the rapid connection of multiple connecting leads to the detonation control unit. Furthermore, the multiple wire clamps are placed inside the housing, facilitating their placement and preventing them from being submerged in water. Additionally, a waterproof aviation connector is installed on the housing. One end of the waterproof aviation connector extends out of the housing and into the hollow cavity to form a conductive connection end. This facilitates the electrical connection of the wire clamps to the detonation control unit installed in the hollow cavity through control busbar 1, control busbar 2, and the waterproof aviation connector. The relatively sealed relationship between the hollow cavity 1 and the hollow cavity 2 helps ensure the stability and reliability of the detonation control unit's operation.

[0038] According to one embodiment of this application, the underwater electronic detonator detonation control device further includes:

[0039] A counterweight is installed inside the hollow cavity and located at the lower part of the hollow cavity.

[0040] In this embodiment, a counterweight is installed inside the hollow cavity. The center of gravity of the underwater electronic detonator detonation control device is adjusted by the counterweight. When the underwater electronic detonator detonation control device floats in the water, the floating attitude of the underwater electronic detonator detonation control device can be balanced, reducing the excessive tilting or overturning of the floating attitude of the underwater electronic detonator detonation control device due to the influence of wind, waves and water flow, so that the floating attitude of the underwater electronic detonator detonation control device in the water is suitable.

[0041] According to one embodiment of this application, the underwater electronic detonator detonation control device further includes:

[0042] The mounting support plate is horizontally installed inside the hollow cavity.

[0043] Multiple shock-absorbing damping components are provided, with the lower ends of the multiple shock-absorbing damping components connected to the mounting support plate and the upper ends of the multiple shock-absorbing damping components extending upward. The detonation control unit is installed between the upper ends of the multiple shock-absorbing damping components and is suspended and supported by the multiple shock-absorbing damping components.

[0044] In this embodiment, the detonation control unit is installed between the upper ends of multiple shock-absorbing damping components and is suspended and supported by multiple shock-absorbing damping components. The shock-absorbing damping components play a shock-absorbing role. When the underwater electronic detonator detonation control device floats in the water, it reduces the vibration generated by the detonation control unit and prevents damage to the components inside the detonation control unit due to excessive vibration.

[0045] According to one embodiment of this application, the underwater electronic detonator detonation control device further includes:

[0046] A lifting counterweight body is connected to the lower end of the lower half shell, and a water storage cavity is formed inside the lifting counterweight body;

[0047] A water pump is connected to the lifting counterweight body. The water pump has a water delivery pipe that is connected to the bottom of the water storage chamber. The water pump can input water into the water storage chamber and can also pump water out of the water storage chamber.

[0048] In this embodiment, a lifting counterweight body is connected to the lower end of the lower half of the shell. A water-filled cavity is formed inside the lifting counterweight body. By connecting a pump to the lifting counterweight body, water can be pumped into the water-filled cavity to increase the water volume and cause the underwater electronic detonator detonation control device to descend in the water. Alternatively, the water pump can be used to pump water out of the water-filled cavity to reduce the water volume and cause the underwater electronic detonator detonation control device to rise in the water. This facilitates adjustment of the underwater electronic detonator detonation control device's setting depth in the water, allowing it to be set at a more suitable depth and ensuring reliable detonation control of electronic detonators placed at different depths.

[0049] According to another aspect of this application, a method for controlling the detonation of an underwater electronic detonator is provided, the method comprising:

[0050] Multiple electronic detonators were deployed in the underwater blasting area;

[0051] The above-mentioned underwater electronic detonator detonation control device is arranged in the water, the detonation control unit is connected to the detonation control platform, and the multiple electronic detonators arranged underwater are connected to the detonation control unit.

[0052] The detonation control platform sends a detonation control command to the detonation control unit. The detonation control unit receives the detonation control command from the detonation control platform and controls the multiple electronic detonators that are communicatively connected to the detonation control unit to detonate based on the received detonation control command.

[0053] In this embodiment of the underwater electronic detonator detonation control method, the aforementioned underwater electronic detonator detonation control device is arranged in the water, which facilitates the detonation control of multiple electronic detonators arranged underwater, and avoids the detonation control unit from being wetted by surging waves. It also prevents the detonation control unit from being submerged in water, thereby improving the reliability of the underwater electronic detonator detonation control system for underwater blasting.

[0054] According to one embodiment of this application, the underwater electronic detonator detonation control method further includes:

[0055] A lifting counterweight body is connected to the lower end of the lower half shell, wherein a water storage cavity is formed within the lifting counterweight body;

[0056] According to the depth requirements for arranging the underwater electronic detonator detonation control device, the amount of water stored in the water storage chamber is adjusted so that the underwater electronic detonator detonation control device floats or sinks in the water, and the underwater electronic detonator detonation control device is arranged at a suitable depth in the water.

[0057] In this embodiment of the underwater electronic detonator detonation control method, a lifting counterweight body is connected to the lower end of the lower half shell. A water storage cavity is formed inside the lifting counterweight body. This allows the amount of water stored in the water storage cavity to be adjusted according to the depth position requirements of the underwater electronic detonator detonation control device. This facilitates setting the underwater electronic detonator detonation control device at a more suitable depth in the water, thus satisfying the need for reliable detonation control of electronic detonators arranged at different depths.

[0066] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0067] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0068] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0069] One aspect of this application provides an underwater electronic detonator initiation control device, such as... Figures 1 to 6 As shown, it includes:

[0070] The lower half shell 1 has a hollow cavity 1 inside it. The upper opening of the hollow cavity 1 forms an open end 1. The outer wall of the peripheral side of the open end 1 is connected to an annular protrusion 10.

[0071] The upper shell 2 has a hollow cavity 2 inside it. The lower side of the hollow cavity 2 is open to form an open end 2. The outer wall of the open end 2 is connected to an annular protrusion 20. The upper shell 2 covers the upper side of the lower shell 1. The annular protrusion 20 is set directly opposite the annular protrusion 10. The hollow cavity 2 and the hollow cavity 1 are connected to form an installation cavity.

[0072] The detonation control unit 9 is installed in the mounting cavity. The detonation control unit 9 is used to communicate with the electronic detonator and to control the detonation of the electronic detonator that is communicated with it.

[0073] A sealing assembly is installed between annular protrusion 10 and annular protrusion 20;

[0074] The locking mechanism is connected between the lower half-shell 1 and the upper half-shell 2. The locking mechanism can lock the upper half-shell 2 and the lower half-shell 1 together, so that the sealing assembly seals the gap between the annular protrusion 10 and the annular protrusion 20, forming a sealed space in the installation cavity.

[0075] In this embodiment, as Figures 1 to 6As shown, in this embodiment, the outer wall of the open end 1 of the lower half shell 1 is connected to an annular protrusion 10, and the outer wall of the open end 2 of the upper half shell 2 is connected to an annular protrusion 20. A sealing assembly is installed between the annular protrusion 10 and the annular protrusion 20, and the locking mechanism can lock the upper half shell 2 and the lower half shell 1 together, so that the sealing assembly seals the gap between the annular protrusion 10 and the annular protrusion 20, forming a sealed space in the installation cavity. Therefore, when the underwater electronic detonator detonation control device in this embodiment is placed in water for detonation control of the underwater electronic detonator, the detonation control unit 9 is installed in the installation cavity, which prevents the detonation control unit 9 from being wetted by the waves and also prevents the detonation control unit 9 from being submerged in water, thereby improving the reliability of the underwater electronic detonator detonation control device for underwater blasting. Furthermore, in this embodiment, the upper half-shell 2 and the lower half-shell 1 are locked together by a locking mechanism. After the detonation control unit 9 is arranged in the installation cavity, the upper half-shell 2 and the lower half-shell 1 can be locked together by the locking mechanism, so that the sealing assembly seals the gap between the annular protrusion 10 and the annular protrusion 20, which facilitates the arrangement of the detonation control unit 9 and helps to ensure the reliability of the detonation control unit 9 in terms of waterproofing.

[0076] In this embodiment, as Figures 1 to 3 As shown, in this embodiment, the lower half-shell 1 is approximately hemispherical in shape, and the annular protrusion 10 is circular in shape. In order to improve the reliability of the connection between the annular protrusion 10 and the lower half-shell 1, multiple reinforcing protrusions 102 are circumferentially spaced on the lower side of the annular protrusion 10. The reinforcing protrusions 102 are connected between the lower side of the annular protrusion 10 and the outer wall of the lower half-shell 1.

[0077] Furthermore, such as Figures 1 to 3 As shown, in this embodiment, the upper shell 2 has a hemispherical structure, and the annular protrusion 20 has a circular structure. In order to improve the reliability of the connection between the annular protrusion 20 and the upper shell 2, multiple reinforcing protrusions 202 are circumferentially spaced on the upper side of the annular protrusion 20. The reinforcing protrusions 202 are connected between the upper side of the annular protrusion 20 and the outer wall of the upper shell 2.

[0078] In this embodiment, as Figures 1 to 4As shown, the locking mechanism in this embodiment includes multiple tightening and stopping mechanisms 4, which are circumferentially spaced between the annular protrusion 10 and the annular protrusion 20. Specifically, the tightening and stopping mechanism 4 includes a rotating connecting arm 40, a rotating connecting shaft 41, and a tightening and stopping top. Multiple rotating support plates 101 are circumferentially spaced on the lower side of the annular protrusion 10. Each pair of adjacent rotating support plates 101 is arranged in pairs, and two shaft holes 1011 are formed opposite each other on the paired rotating support plates 101. The rotating connecting shaft 41 is installed in the two shaft holes 1011 and located between the two rotating support plates 101. The rotating connecting shaft 41 passes through both ends of the rotating support plate 101 and is connected to limiting protrusions 411. Furthermore, in this embodiment, the rotating connecting arm 40 is approximately U-shaped. The lower part of the rotating connecting arm 40 is a connecting head with a rotating connecting through hole. The rotating connecting arm 40 is installed between the two rotating support plates 101, and the rotating connecting shaft 41 passes through the rotating connecting through hole. Further, the rotating connecting... The middle part of the arm 40 is a connecting straight plate, and the upper part of the rotating connecting arm 40 is a connecting support plate with a threaded through hole. In this embodiment, the tightening stop includes a knob 42 and a screw 421. The screw 421 is connected to the knob 42 and threadedly connected to the threaded through hole. The lower end of the screw 421 passes through the connecting support plate. Rotating the rotating connecting arm 40 toward the upper housing 2 causes the connecting straight plate of the rotating connecting arm 40 to stop against the inner wall of the recessed groove provided on the second annular protrusion 20 and the first annular protrusion 10. By rotating the knob 42, the lower end of the screw 421 can stop against the upper side of the second annular protrusion 20, thereby applying a clamping force to the second annular protrusion 20 and the first annular protrusion 10. This causes the sealing assembly installed between the first annular protrusion 10 and the second annular protrusion 20 to seal the gap between the first annular protrusion 10 and the second annular protrusion 20.

[0079] Furthermore, such as Figures 3 to 6 As shown, in this embodiment, in order to improve the reliability of the tightening and stopping mechanism 4 in applying clamping force to the second annular protrusion 20 and the first annular protrusion 10, an annular connecting plate 43 is connected to the lower end of the screw 421. The annular connecting plate 43 is fixedly connected to the lower end of the screw 421 by a screw 45. An elastic pad 44 is connected to the lower end of the annular connecting plate 43. The elastic pad 44 is bonded to the lower end of the annular connecting plate 43. By rotating the knob 42, the elastic pad 44 can stop on the upper side of the second annular protrusion 20 and generate elastic deformation, thereby improving the reliability of the tightening and stopping mechanism 4 in applying clamping force to the second annular protrusion 20 and the first annular protrusion 10.

[0080] Furthermore, such as Figures 3 to 6As shown, in this embodiment, multiple limiting protrusions 201 are provided on the upper side of the annular protrusion 20, facing the multiple rotating support plates 101. Each pair of adjacent limiting protrusions 201 are arranged in pairs, and the paired limiting protrusions 201 can limit the elastic pad 44 in the circumferential direction. In addition, the limiting protrusions 201 can also improve the reliability of the connection between the annular protrusion 20 and the upper shell 2.

[0081] It should be noted that the locking mechanism in this embodiment can also use other locking devices or locking components, which can be connected between the annular protrusion 10 and the annular protrusion 20, so that the sealing assembly installed between the annular protrusion 10 and the annular protrusion 20 can seal the space between the annular protrusion 10 and the annular protrusion 20.

[0082] In this embodiment, as Figure 3 As shown, the detonation control unit 9 in this embodiment includes an electrical enclosure 90 and an energy storage capacitor 91, a first control circuit board 92, and a second control circuit board 93 disposed within the electrical enclosure 90. Multiple electronic components are respectively disposed on the first control circuit board 92 and the second control circuit board 93. These multiple electronic components are not illustrated in this embodiment. Furthermore, the specific types and models of the multiple electronic components can be arranged according to control requirements and with reference to existing technologies, and will not be elaborated upon here.

[0083] Furthermore, in this embodiment, the underwater electronic detonator detonation control device is powered by an energy storage capacitor 91, and control circuit board one 92 and control circuit board two 93 are connected to the energy storage capacitor 91 by wires. Alternatively, the energy storage capacitor 91 can be replaced by a mobile power supply or battery pack, which facilitates the supply of power to control circuit board one 92, control circuit board two 93 and multiple electronic components to achieve detonation control.

[0084] Furthermore, such as Figures 1 to 3 As shown, the top of the upper shell 2 in this embodiment is also provided with a power button 28. The power button 28 is electrically connected to the detonation control unit 9 via a cable, and the underwater electronic detonator detonation control device can be turned on and off by the power button 28. Furthermore, the top of the upper shell 2 in this embodiment is also connected with a handle 27, which facilitates the movement or arrangement of the underwater electronic detonator detonation control device by means of the handle 27. Furthermore, the bottom of the lower shell 1 in this embodiment is connected with a lifting ring 18, which facilitates the attachment of the underwater electronic detonator detonation control device to the anchor and the arrangement of the underwater electronic detonator detonation control device in a designated position in the water.

[0085] One embodiment of this application, such as Figures 1 to 5 As shown, the underwater electronic detonator detonation control device also includes:

[0086] The connecting leads 5 are provided with multiple leads spaced around the perimeter, and one end of each connecting lead 5 is electrically connected to the detonation control unit 9;

[0087] A waterproof isolation cover 3 is installed between open end one and open end two. The waterproof isolation cover 3 includes a cover body 30, an inner annular baffle 31, an inclined connecting ring 32, and an outer annular baffle 33. The inner annular baffle 31 is connected to the periphery of the cover body 30 and extends outward. One end of the inclined connecting ring 32 is connected to the inner annular baffle 31. The cover body 30, the inner annular baffle 31, and the inclined connecting ring 32 are located in the installation cavity. The outer annular baffle 33 is connected to the other end of the inclined connecting ring 32 and is installed between annular protrusion one 10 and annular protrusion two 20.

[0088] The sealing assembly includes:

[0089] An annular elastic sealing ring 11 is installed between the annular protrusion 10 and the outer annular baffle 33. The annular elastic sealing ring 11 elastically squeezes and seals the gap between the annular protrusion 10 and the outer annular baffle 33.

[0090] The second annular elastic sealing ring is installed between the second annular protrusion 20 and the outer annular baffle 33. The second annular elastic sealing ring elastically squeezes and seals the gap between the second annular protrusion 20 and the outer annular baffle 33. The other end of each connecting leg 5 passes through the second annular elastic sealing ring and extends outward.

[0091] In this embodiment, as Figures 1 to 5 As shown, in this embodiment, the connection point between one end of the connecting lead 5 and the detonation control unit 9 is located inside the mounting cavity, preventing the connection point from being submerged in water and improving the stability and reliability of the electrical connection between the connecting lead 5 and the detonation control unit 9. Furthermore, in this embodiment, a waterproof isolation cover 3 is installed between the first and second open ends. The waterproof isolation cover 3 divides the mounting cavity into an upper and lower cavity, facilitating the arrangement of electronic components or other parts in the upper and lower cavity respectively, reducing mutual interference between these components. Furthermore, the annular elastic sealing ring 11 elastically compresses and seals the gap between the annular protrusion 10 and the outer annular baffle 33, and the annular elastic sealing ring 20 elastically compresses and seals the gap between the annular protrusion 20 and the outer annular baffle 33, improving the reliability of the seal between the lower housing 1 and the upper housing 2. Additionally, the connecting lead 5 extends through the annular elastic sealing ring 2, facilitating the arrangement of the connecting lead 5.

[0092] Furthermore, such as Figures 3 to 5As shown, in this embodiment, the upper side of the annular protrusion 10 is provided with an annular mounting groove, and the annular elastic sealing ring 11 is installed in the annular mounting groove. In addition, in this embodiment, the annular mounting groove is a circular groove structure, and the annular elastic sealing ring 11 is circular. Furthermore, the annular mounting groove and the annular elastic sealing ring 11 can also be configured as other ring shapes.

[0093] Furthermore, such as Figure 4 As shown, in this embodiment, in order to improve the sealing performance of the annular elastic sealing ring 11 for the elastic compression seal between the annular protrusion 10 and the outer annular baffle 33, a stop-top protrusion 333 is provided on the lower side of the outer annular baffle 33 directly opposite the annular mounting groove. When the upper half housing 2 and the lower half housing 1 are locked together by the locking mechanism, the stop-top protrusion 333 is pressed into the annular elastic sealing ring 11, so that the annular elastic sealing ring 11 forms an annular recess, thereby improving the sealing performance of the annular elastic sealing ring 11 for the elastic compression seal between the annular protrusion 10 and the outer annular baffle 33.

[0094] Furthermore, such as Figure 5 As shown, in this embodiment, the outer annular baffle 33 is fixedly connected to the annular protrusion 10 by multiple screws 332. The multiple screws 332 are circumferentially spaced along the extending direction of the outer annular baffle. By tightening the multiple screws 332, the outer annular baffle 33 and the annular protrusion 10 compress the annular elastic sealing ring 11, causing the stop protrusion 333 to be pressed into the annular elastic sealing ring 11. Furthermore, in this embodiment, both the inner annular baffle 31 and the outer annular baffle 33 are disc-shaped. In addition, the waterproof isolation cover 3 in this embodiment can also be configured with other structures to facilitate the division of the installation cavity into an independent upper cavity and a lower cavity.

[0095] One embodiment of this application, such as Figure 3 and Figure 4 As shown, the second annular elastic sealing ring includes:

[0096] The first annular elastic sealing ring 34 is installed on the upper side of the outer annular baffle 33;

[0097] The second annular elastic sealing ring 21 is installed on the lower side of the annular protrusion 20, directly opposite the first annular elastic sealing ring 34, and is elastically compressed against the first annular elastic sealing ring 34. Each connecting wire 5 passes through the gap between the first annular elastic sealing ring 34 and the second annular elastic sealing ring 21. The first annular elastic sealing ring 34 and the second annular elastic sealing ring 21 elastically compress and seal the gap between them, and the first annular elastic sealing ring 34 and the second annular elastic sealing ring 21 elastically compress and seal the gap between each connecting wire 5 and the gap between them.

[0098] In this embodiment, as Figure 3 and Figure 4 As shown, the second annular elastic sealing ring in this embodiment includes a second annular elastic sealing ring 34 and a second annular elastic sealing ring 21. Each connecting lead 5 passes through the first annular elastic sealing ring 34 and the second annular elastic sealing ring 21, which facilitates the flexible arrangement of multiple connecting leads 5 and can adapt to the needs of arranging different numbers of connecting leads 5.

[0099] In this embodiment, as Figures 3 to 5 As shown, the outer annular baffle 33 is horizontally connected to the outside of the inclined connecting ring 32. The upper side of the outer annular baffle 33 is provided with an annular mounting groove 331, and the first annular elastic sealing ring 34 is installed in the annular mounting groove 331. The lower side of the annular protrusion 20 is provided with an annular mounting groove 331, and the second annular elastic sealing ring 21 is installed in the annular mounting groove 331. When the upper half shell 2 and the lower half shell 1 are locked together by the locking mechanism, the first annular elastic sealing ring 34 and the second annular elastic sealing ring 21 are squeezed against each other and generate elastic deformation, sealing the gap between the annular protrusion 10 and the annular protrusion 20, forming the first seal. Furthermore, in this embodiment, both the second annular mounting groove 331 and the third annular mounting groove are circular annular groove structures. Correspondingly, the second annular elastic sealing ring 34 and the second annular elastic sealing ring 21 are both circular rings. In addition, the second annular mounting groove 331, the third annular mounting groove, the second annular elastic sealing ring 34 and the second annular elastic sealing ring 21 can also be configured as other ring shapes.

The mounting guide posts 103 extend vertically upward. The outer annular baffle 33 is provided with two mounting positioning through holes 1 facing the two mounting guide posts 103 respectively. During the process of limiting the waterproof isolation cover 3 to be installed on the upper side of the lower half-shell 1, the two mounting positioning through holes 1 are aligned with the two mounting guide posts 103 before installation, so that the mounting guide posts 103 are inserted into the mounting positioning through holes 1. In addition, the annular protrusion 20 is provided with two mounting positioning through holes 2 facing the two mounting guide posts 103 respectively. During the process of installing the upper half-shell 2 on the upper side of the waterproof isolation cover 3, the two mounting positioning through holes 2 are aligned with the two mounting guide posts 103 before installation, so that the mounting guide posts 103 are inserted into the mounting positioning through holes 2, thereby accurately installing the waterproof isolation cover 3 and the upper half-shell 2 with the lower half-shell 1.

[0101] One embodiment of this application, such as Figures 3 to 5 As shown, the underwater electronic detonator detonation control device also includes:

[0102] An elastic wire clamping ring 6 is installed on the outer periphery of the inclined connecting ring 32. Multiple wire clamping grooves 60 are provided circumferentially at intervals on the outer wall of the elastic wire clamping ring 6, corresponding to multiple connecting leads 5. The multiple connecting leads 5 are respectively clamped into the wire clamping grooves 60. The inner wall of the elastic wire clamping ring 6 elastically compresses the outer wall of the inclined connecting ring 32, elastically compressing and sealing the gap between the inner wall of the elastic wire clamping ring 6 and the outer wall of the inclined connecting ring 32. The outer wall of the elastic wire clamping ring 6 elastically compresses the inner wall of the upper housing 2, elastically compressing and sealing the gap between the outer wall of the elastic wire clamping ring 6 and the inner wall of the upper housing 2. Furthermore, the inner wall of the wire clamping groove 60 compresses the connecting leads 5 located within the wire clamping groove 60, elastically compressing and sealing the gap between the inner wall of the wire clamping groove 60 and the outer wall of the connecting leads 5.

[0103] In this embodiment, as Figures 3 to 5 As shown, in this embodiment, an elastic wire clamping ring 6 is installed on the outer periphery of the inclined connecting ring 32, which facilitates the clamping of the connecting lead 5 into the wire clamping groove 60, thereby limiting the position of the connecting lead 5. It also facilitates the compression of the connecting lead 5 by the elastic deformation of the elastic wire clamping ring 6, thereby fixing the connecting lead 5. Furthermore, the inner wall of the elastic wire clamping ring 6 is elastically compressed with the outer wall of the inclined connecting ring 32, and the outer wall of the elastic wire clamping ring 6 is elastically compressed with the inner wall of the upper half shell 2, so that a second seal is formed between the elastic wire clamping ring 6 and the inner wall of the inclined connecting ring 32 and the upper half shell 2, preventing water from seeping into the installation cavity along the connecting lead 5.

[0104] In this embodiment, as Figures 3 to 5As shown, the wire-clamping groove 60 is disposed on the circumferential outer wall of the elastic wire-clamping ring 6 and extends through the top of the elastic wire-clamping ring 6. Before arranging the connecting leads 5, elastic wire-clamping rings 6 with the same number of wire-clamping grooves 60 are selected according to the number of connecting leads 5 to be arranged. After the elastic wire-clamping ring 6 is installed on the outer periphery of the inclined connecting ring 32, multiple connecting leads 5 are respectively clamped into the wire-clamping grooves 60. Furthermore, in this embodiment, the lower end of the inclined connecting ring 32 is expanded outward relative to the upper end, so that the inner sidewall of the upper half shell 2 can elastically compress the outer sidewall of the elastic wire-clamping ring 6.

[0105] Furthermore, such as Figure 3 and Figure 6 As shown, in this embodiment, to facilitate the positioning of multiple connecting leads 5 extending into the hollow cavity 2, a locking line 37 is installed on the upper side of the inner annular baffle 31. The locking line 37 includes a connecting base plate 371 and locking protrusions 372. The locking protrusions 372 are connected in pairs to the upper side of the connecting base plate 371, and a limiting groove is formed between the two pairs of locking protrusions 372. One end of the connecting lead 5 is locked into the limiting groove. The multiple limiting grooves formed on the locking line 37 are respectively set to face the multiple locking through slots 60. Furthermore, the connecting base plate 371 is fixedly installed on the upper side of the inner annular baffle 31 by multiple screws 373. In addition, this embodiment has four locking lines 37, and the number of locking lines 37 can be adjusted as needed.

[0106] One embodiment of this application, such as Figure 3 and Figure 4 As shown, a stop protrusion is provided on the inner wall of the upper shell 2, directly opposite the inner annular baffle 31. The stop protrusion protrudes horizontally towards the inner side of the hollow cavity 2 and is located above the inner annular baffle 31. The sealing assembly also includes:

[0107] The third annular elastic sealing ring is installed between the inner annular baffle 31 and the stop protrusion. The inner annular baffle 31 and the stop protrusion compress the third annular elastic sealing ring, causing the third annular elastic sealing ring to undergo elastic deformation and elastically compress and seal the gap between the inner annular baffle 31 and the stop protrusion. The connecting wire 5 passes through the third annular elastic sealing ring.

[0108] In this embodiment, as Figure 3 and Figure 4 As shown, in this embodiment, an annular elastic sealing ring three is installed between the inner annular baffle 31 and the stop protrusion. The annular elastic sealing ring three undergoes elastic deformation and elastically squeezes and seals the gap between the inner annular baffle 31 and the stop protrusion, forming a third seal, which further prevents water from entering the installation cavity.

[0109] In this embodiment, as Figure 3 and Figure 4As shown, the annular elastic sealing ring three includes:

[0110] The first annular elastic sealing ring 35 is disposed on the upper side of the inner annular baffle 31;

[0111] The second annular elastic sealing ring 37 is positioned directly opposite the first annular elastic sealing ring 35 on the lower side of the stop protrusion. Each connecting lead 5 passes through the gap between the first annular elastic sealing ring 35 and the second annular elastic sealing ring 37. The first annular elastic sealing ring 35 and the second annular elastic sealing ring 37 elastically compress and seal the gap between them. Furthermore, the first annular elastic sealing ring 35 and the second annular elastic sealing ring 37 elastically compress and seal the gap between each connecting lead 5 and the gap between the first annular elastic sealing ring 35 and the second annular elastic sealing ring 37, respectively.

[0112] In this embodiment, as Figure 3 and Figure 4 As shown, in this embodiment, the upper side of the inner annular baffle 31 is provided with an annular mounting groove 311, and the first annular elastic sealing ring 35 is installed in the annular mounting groove 311. The annular mounting groove 311 has a circular groove structure.

[0113] In this embodiment, as Figure 3 and Figure 4 As shown, in this embodiment, to ensure uniform pressure application to the first annular elastic sealing ring 35 and the second annular elastic sealing ring 7, a stop ring 8 is provided to stop and compress the second annular elastic sealing ring 7. Specifically, in this embodiment, the upper half of the shell 2 has multiple stop protrusions 23 spaced circumferentially on its peripheral sidewall, and the lower ends of the multiple stop protrusions 23 form a stop surface. The upper half of the shell 2 also has multiple connecting support columns 22 spaced circumferentially on its peripheral sidewall. The stop ring 8 is fixedly connected to the lower ends of the multiple connecting support columns 22 by screws 2 80, and the upper side of the stop ring 8 and the stop surface formed by the lower ends of the multiple stop protrusions 23 stop the pressure. When the upper half of the shell 2 and the lower half of the shell 1 are locked together by the locking mechanism, the sealing assembly seals the gap between the annular protrusion 10 and the annular protrusion 20. The stop ring 8 applies pressure to the second annular elastic sealing ring 7, causing compression and deformation between the first annular elastic sealing ring 35 and the second annular elastic sealing ring 7. In this embodiment, the stop ring 8 and multiple stop protrusions 23 together constitute a stop protrusion. Furthermore, the stop protrusion in this embodiment can also be configured with other structures. Further, in this embodiment, both the first annular elastic sealing ring 35 and the second annular elastic sealing ring 7 are circular in shape.

[0114] It should be noted that when multiple connecting leads 5 are arranged, there is a risk that water may seep into the installation cavity along the connecting leads 5 when the underwater electronic detonator detonation control device is placed in water. Moreover, the location where the connecting leads 5 are arranged is also the most difficult to reliably waterproof. In this embodiment, the underwater electronic detonator detonation control device forms three seals: a first seal, a second seal, and a third seal. These three seals prevent water from seeping into the installation cavity along the connecting leads 5, ensuring the reliability of the underwater electronic detonator detonation control device's waterproofing.

[0116] The wire clamps are provided in multiple ways, each corresponding to a number of connecting leads 5. One end of each connecting lead 5 extends into the hollow cavity 2. The end of each connecting lead 5 extending into the hollow cavity 2 is connected to a wire clamp and is electrically connected. The multiple wire clamps are placed in the placement cavity 301.

[0117] Waterproof aviation plug 36 is installed on the cover 30. One end of the waterproof aviation plug 36 extends out of the cover 30 and into the hollow cavity to form a conductive connection end 1. The other end of the waterproof aviation plug 36 extends into the placement cavity 301 to form a conductive connection end 2.

[0120] In this embodiment, as Figure 3 and Figure 5As shown, in this embodiment, the connecting leads 5 are electrically connected to the detonation control unit 9 via wire clamps. This facilitates operation and reduces the difficulty and workload of electrically connecting the connecting leads 5 to the detonation control unit 9. It also allows for the rapid electrical connection of multiple connecting leads 5 to the detonation control unit 9. Furthermore, multiple wire clamps are placed inside the placement cavity 301, which facilitates placement of the wire clamps and prevents them from being submerged in water. In addition, a waterproof aviation plug 36 is installed on the cover 30. One end of the waterproof aviation plug 36 extends out of the cover 30 and into the hollow cavity to form a conductive connection end. This facilitates the electrical connection of the wire clamps to the detonation control unit 9 installed in the hollow cavity through the control bus 1, control bus 2, and waterproof aviation plug 36. It also ensures a relative seal between the hollow cavity 1 and the hollow cavity 2, which helps to ensure the stability and reliability of the detonation control unit 9.

[0125] In this embodiment, as Figure 3As shown, in this embodiment, a counterweight is installed inside the hollow cavity. The center of gravity of the underwater electronic detonator detonation control device is adjusted by the counterweight. When the underwater electronic detonator detonation control device floats in the water, the floating attitude of the underwater electronic detonator detonation control device in the water can be balanced, reducing the floating attitude of the underwater electronic detonator detonation control device from being excessively tilted or overturned due to the influence of wind, waves and water flow, so that the floating attitude of the underwater electronic detonator detonation control device in the water is suitable.

[0126] In this embodiment, as Figure 3 As shown, the counterweight in this embodiment includes a first counterweight 16 and a second counterweight 17. Both the first counterweight 16 and the second counterweight 17 are rectangular plate structures and are connected by bolts. Specifically, support protrusions 15 are connected to the left and right sides of the inner bottom wall of the lower shell 1. The support protrusions 15 extend into the hollow cavity 1, and the first counterweight 16 and the second counterweight 17 are installed on the upper side of the two support protrusions 15 by bolts. Furthermore, the structure of the counterweight in this embodiment and the way it is installed in the hollow cavity 1 can be varied to facilitate the floating posture of the underwater electronic detonator detonation control device in the water.

By connecting a pump to the lifting counterweight body, water can be pumped into the water-filled cavity to increase the water volume and cause the underwater electronic detonator detonation control device to descend in the water. Alternatively, the water pump can be used to pump water out of the water-filled cavity to reduce the water volume and cause the underwater electronic detonator detonation control device to rise in the water. This facilitates adjustment of the underwater electronic detonator detonation control device's setting depth in the water, allowing it to be set at a more suitable depth and satisfying the requirement for reliable detonation control of electronic detonators placed at different depths.

[0136] In this embodiment, the lifting counterweight body is connected to the lower end of the lower half-shell 1. The lifting counterweight body can be connected to the lifting ring 18.
